SAVE THESE INSTRUCTIONS!

Keep this manual with the tool for use by the operator.

Digital Clamp Meter Safety

• Use caution when working with voltages above 30 V AC RMS, 42 V AC peak or 60 V DC. These voltages pose serious shock hazard. High-voltage circuits, both DC and AC, are very dangerous and should be measured with great care. Avoid working alone.
• Do not connect to voltages that exceed 600 VAC or VDC relative to earth ground. This may damage the meter and expose the operator to a shock hazard.
• When using the probes, keep your fingers behind the finger guards on the probes. This reduces the risk of electric shock.
• Never ground yourself when taking electrical measurements. Do not touch ex-

posed metal pipes, outlets, fixtures, etc., which might be at ground potential. Keep your body isolated from ground using appropriate methods.

• Disconnect the test leads from the meter before making current clamp measurements. This reduces the risk of electric shock.
• When measuring resistance, disconnect all power (remove batteries, unplug cord, discharge all capacitors, etc.) to the circuit being measured. This reduces the risk of electric shock.
  • After resistance test, the capacitive circuits must be discharged. This will help protect against electric shock.
• Use extreme caution when working near bare conductors and bus bars. Accidental contact with conductors could result in electrical shock.
• Turn OFF power to the circuit under test before cutting, unsoldering, or breaking the circuit. Small amount of current can expose the operator to a shock hazard.

The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), this is a stylistic or background line, not a placeholder underscore. Therefore, the OCR result must ignore it and output nothing or only meaningful text. The provided OCR content is "____", which consists of four underscores. This is an incorrect interpretation of the line as a placeholder, violating the rule that stylistic lines must be ignored. The OCR has hallucinated underscores where none should exist based on the GT's visual context. Hence, the OCR result is inconsistent with the Ground Truth.

Set-Up and Operation

WARNING

Set up and operate the micro CM-100 Digital Clamp Meter according to these procedures to reduce the risk of injury from electric shock and other causes, and prevent tool damage.

Use caution when working with voltages above 30 V AC RMS,

42V AC peak or 60V DC. These voltages pose serious shock hazard. High-voltage circuits, both DC and AC, are very dangerous and should be measured with great care. Avoid working alone.

Do not connect to voltages that exceed 600 VAC or VDC relative to earth ground. This may damage the meter and expose the operator to a shock hazard.

When using the probes, keep your fingers behind the finger guards on the probes. This reduces the risk of electric shock.

Never ground yourself when taking electrical measurements. Do not touch exposed metal pipes, outlets, fixtures, etc., which might be at ground potential. Keep your body isolated from ground using appropriate methods.

Use extreme caution when working near bare conductors and bus bars. Accidental contact with conductors could result in electrical shock.

1. Check for an appropriate work area as indicated in the General Safety section.
2. Inspect the work to be done and confirm that you have correct equipment for the application. See the Specifications section for range, accuracy and other information.
3. To select a function, turn the rotary function switch to the appropriate position.
4. Select the proper function and range for your measurement.
5. Determine the voltage to be measured. Do not apply more than the rated voltage, as marked on the meter, between terminals or between any terminal and earth ground.
6. Check the clamps for full closure. Do not use the meter if the clamps do not operate properly.

7. Turn the function switch to the OFF position after inspection.

8. Make sure all equipment being used has been properly inspected.

9. Use correct accessories for the application. Select the proper terminals, function, and range for all measurements.

10. When making electrical connections, connect the common test lead (black) before connecting the live test lead (red); when disconnecting, disconnect the live test lead (red) before disconnecting the common test lead (black).

11. If "OL" appears in the display during a measurement, the value exceeds the range you have selected, change to a higher range. On some low DC and AC voltage ranges, with the test leads not connected to a device, the display may show a random, changing reading. This is normal and is caused by the high-input sensitivity. The reading will stabilize and give a proper measurement when connected to the circuit.

12. Always turn the function switch to the OFF position when the meter is not in use. The meter will automatically shut OFF if not used for 20 minutes.

Rotary Function Switch

The Rotary Function switch permits the user to select a measurement function by positioning the rotary switch to one of the icons around its perimeter.

Temperature Measurement

⚠ WARNING To reduce the risk of electric shock, disconnect both test probes from any source of voltage before making a temperature measurement.

1. Set the function switch to Temp position. The meter automatically defaults to °C range.
2. Insert the temperature adapter in "COM" and "V Ω CAP TEMP Hz" terminal with

-ve side in "COM" and +ve side in "V Ω CAP TEMP Hz" terminal.

1. Insert the Temperature Probe into the adapter.
2. Touch the Temperature Probe head to the part whose temperature is to be measured. Keep the probe in contact with the part under test until the reading stabilizes (about 30 seconds).
3. Read the temperature in the display. The digital reading will indicate the proper value with decimal point.
4. Press MODE button to change from °C to °F unit.

WARNING To reduce risk of electric shock, be Figure 9 – Temperature Probe sure the thermocouple has been removed before changing to another measurement function.
