- Seven preparation topics define the scope: Bluetooth app, web server, and five transmitter types.
- Every domain starts with "configure and monitor," so hands-on familiarity matters more than memorized definitions.
- No verified passing score, fee, question count, or timer exists in public sources; confirm with your testing member.
What This Cheat Sheet Covers (and What It Doesn't)
This is a one-page style review of the facts that define Process Measurement Instrumentation 2 (C-262). It is built from the scope that SACA's linked registry description publishes, not from leaked questions or an official handbook. That distinction matters. The seven topics below are unweighted preparation topics, not a formal exam blueprint, and no public source verifies how many items each one receives.
If you are brand new to the credential, start with What Is C-262? and then return here. If you want the long-form walkthrough of each content area, the C-262 Exam Domains guide goes deeper than a cheat sheet can. For a full plan, see the C-262 Study Guide.
C-262 at a Glance: Issuer, Format, and Access
| Item | What is established |
|---|---|
| Credential name | Process Measurement Instrumentation 2 (C-262) |
| Issuer | Smart Automation Certification Alliance (SACA) |
| Scope source | O*NET OnLine certification record, which links to SACA's micro-credential descriptions |
| Program-level assessment model | Silver: online written knowledge assessment. Gold: written knowledge plus hands-on performance assessment |
| Availability signal | SACA's March 31, 2026 announcement names C-262 in pilot-testing communications |
| Question count, timer, passing score, fee, renewal | Not verified in public sources |
The Silver and Gold descriptions are program-level facts about how SACA structures its certifications. They do not confirm which format applies to your specific C-262 sitting, how long it runs, or how appointments work. Treat the testing member (the school or training center administering through SACA's testing portal) as your authority for those details.
The Seven Preparation Domains in One Table
Here is the entire C-262 scope on a single screen. Notice the pattern: five domains are device-specific, and two are about how you reach the device.
| Domain | Preparation topic | Type |
|---|---|---|
| 1 | Use a Bluetooth mobile app to configure and monitor a smart transmitter | Access method |
| 2 | Configure and monitor gauge and absolute smart pressure transmitters | Device |
| 3 | Configure and monitor a temperature transmitter | Device |
| 4 | Configure and monitor a magnetic flow transmitter | Device |
| 5 | Configure and monitor a radar level transmitter | Device |
| 6 | Configure and monitor a Coriolis flow transmitter | Device |
| 7 | Use a web server to configure and monitor a smart transmitter | Access method |
Because no official percentage weighting was verified, do not assume any domain is "worth more." Prepare all seven. Our guide to how hard the C-262 exam is explains why the breadth across five different measurement technologies, rather than depth in any one, is the real challenge.
Domains 1 and 7: Bluetooth App and Web Server Configuration
Domain 1: Bluetooth Mobile App
This domain is about commissioning and diagnosing a smart transmitter from a phone or tablet without a wired handheld communicator.
- Know the workflow: discover the device, pair or connect, authenticate if required, then read and write parameters.
- Understand what "configure" means versus "monitor": setting range, units, damping, and output behavior versus reading live process values and diagnostics.
- Be able to reason about practical limits: short wireless range, line-of-sight and enclosure effects, and why a connection might drop in the field.
- Recognize that changes made through the app alter the device's stored configuration, so verify before you leave the loop.
Domain 7: Web Server
Many modern smart transmitters host an embedded web page. You connect over a network and use a browser as the configuration and monitoring interface.
- Know the basics of reaching a device: it needs a valid network address, and your computer must be on a compatible network.
- Be able to describe what you can see on a device web page: process variables, status and diagnostic messages, and configuration fields.
- Understand the trade-off versus Bluetooth: a web server supports longer-distance or remote access over a network, but introduces network and access-control considerations.
The conceptual overlap between these two domains is large. Both ask the same question: given an access method, how do you safely read and change a smart transmitter's setup? Study them together, then focus on what differs, namely the connection steps and the constraints of each medium.
Domains 2 and 3: Pressure and Temperature Transmitters
Domain 2: Gauge and Absolute Smart Pressure Transmitters
The wording names two pressure types on purpose. Expect the distinction to matter.
- Gauge pressure is measured relative to atmospheric pressure; absolute pressure is measured relative to a vacuum reference.
- Know why the reference matters when you configure range, zero, and units: a mismatch produces an offset that looks like a process problem but is a configuration problem.
- Be comfortable with range setting (lower and upper range values), engineering units, damping, and trim or zero adjustment concepts.
- Know how to monitor: reading the pressure value, checking device status, and spotting out-of-range or fault indications.
Domain 3: Temperature Transmitter
A temperature transmitter conditions a sensor signal and converts it to a standard output.
- Know the common sensor families a transmitter accepts (such as RTDs and thermocouples) and that the transmitter must be told which sensor type is connected.
- Understand wiring configuration considerations for RTDs and why lead resistance affects accuracy.
- Be able to set measurement range, units, and sensor-failure behavior (what the output does if the sensor opens or shorts).
- For thermocouples, understand the role of cold-junction compensation at a conceptual level.
Domains 4, 5, and 6: Magnetic Flow, Radar Level, and Coriolis
These three are the technology-heavy domains. Each rests on a distinct physical principle, and understanding the principle helps you answer configuration questions by reasoning rather than memorizing.
Domain 4: Magnetic Flow Transmitter
Magnetic flowmeters rely on Faraday's law of induction: a conductive liquid moving through a magnetic field generates a voltage proportional to velocity.
- Know the key limitation: the process fluid must be electrically conductive.
- Understand that the pipe must be full for a valid reading, and that grounding and electrode condition affect measurement quality.
- Be able to configure line size, flow range, units, and low-flow cutoff, and to read totalizer and diagnostic values.
Domain 5: Radar Level Transmitter
Radar level devices send microwave energy toward the product surface and measure the reflected signal to infer level.
- Know the geometry vocabulary: tank height or reference point, empty and full calibration, and blocking distance near the antenna.
- Understand why surface conditions, obstructions, and vessel internals can create false echoes, and that signal-quality diagnostics help you spot them.
- Be comfortable with configuring units, damping, and output scaling, and with reading level, distance, and signal-strength values.
Domain 6: Coriolis Flow Transmitter
Coriolis meters measure mass flow directly from the tube motion of vibrating flow tubes, and can also report density and temperature.
- Know that Coriolis is a direct mass-flow measurement, unlike volumetric technologies that infer mass indirectly.
- Understand the secondary measurements available (density, temperature) and why they are useful.
- Be able to configure flow units, cutoffs, and zero calibration, and to recognize why a proper zero procedure depends on a no-flow, full-pipe condition.
- Know typical monitoring items: mass flow, totals, density, and diagnostic alarms such as drive or tube-condition indications.
The Configure-and-Monitor Mindset
Every domain in this credential is phrased as an action: configure, monitor, use. That phrasing suggests the content is procedural and task-oriented. Candidates who have only read about transmitters tend to struggle with sequence questions, such as what you do first, what you verify, and what a status message means.
Build a repeatable mental checklist for each device:
- Identify: What is the device, and what is it measuring?
- Connect: Which interface is in use (Bluetooth app, web server, or another)?
- Configure: Range, units, damping, and device-specific setup.
- Verify: Does the reading match a trusted reference or known process condition?
- Monitor: Which live values and diagnostics indicate healthy operation?
Whether your assessment is written, hands-on, or both depends on the testing member and the level offered. SACA describes Gold as adding a hands-on performance assessment on top of written knowledge, so practicing real or simulated configuration is the safest preparation. Read C-262 Requirements to see what is and is not known about eligibility.
A C-262-Specific Study Sequence
Rather than a generic weekly template, organize your time around how the domains relate. Start with the access methods because they apply to every device, then layer on devices from simplest to most conceptually demanding.
Access methods (Domains 1 and 7)
- Learn the Bluetooth and web-server workflows once, since they reuse across all five devices.
- Practice reading versus writing parameters.
Pressure and temperature (Domains 2 and 3)
- Master gauge versus absolute reference and sensor-type selection.
- These are the most familiar devices and build confidence.
Flow and level (Domains 4, 5, and 6)
- Study the physical principle first, then the configuration fields.
- Spend extra time on Coriolis zeroing and radar echo diagnostics.
Mixed review
- Rotate across all seven topics with scenario-style practice.
- Revisit whichever device feels weakest.
You can test your recall with the practice questions on the main C-262 practice test site. Remember that any question allocation there is editorial and not an official exam weighting.
Facts You Should Not Trust Without Verification
A responsible cheat sheet is as clear about gaps as it is about facts. The following details could not be verified in public sources, so ignore any site that states them with confidence unless it cites the testing member or SACA directly:
- The exact number of questions and the time limit.
- The passing score. See C-262 Passing Score for what is and is not known.
- Exam fees and any retake or renewal rules. Our C-262 Certification Cost article explains why costs depend on the testing member.
- Pass rates. Read C-262 Pass Rate for a careful discussion of why no reliable figure is public.
- Official domain percentages or an exam-version designation.
The same caution applies to career claims. Before you weigh the credential against your goals, review whether C-262 is worth it and the salary guide with that uncertainty in mind. Instrumentation technicians and process-control roles are the natural audience, and the C-262 jobs overview covers how to think about employer demand without inflating it.
Key Takeaway
Build your review around the seven "configure and monitor" tasks, memorize the physical principle behind each device, and treat every number you find online about timing, scoring, or cost as unconfirmed until your testing member says otherwise.
