SAFETY INFORMATION

The Meter complies with:

• UL/IEC/EN 61010-1, CAN/CSA C22.2 No. 61010-1-12, Pollution Degree 2, Measurement Category III 600 V
  • IEC/EN 61010-2-032, CAN/CSA-C22.2 No. 61010-2-032-12
  • EMC IEC/EN 61326-1

Measurement Category III (CAT III) refers to measurements of hard-wired equipment in fixed installations, distribution boards, and circuit breakers. Also includes cables, bus bars, junction boxes, switches, socket outlets in the fixed installation, and stationary motors with permanent connections to fixed installations.

CENELEC Directives

The instruments conform to CENELEC Low-voltage directive 2006/95/EC and Electromagnetic compatibility directive 2004/108/EC.

⚠️ Warning: Read Before Using

To avoid possible electric shock or personal injury:

• Use the Meter only as specified in this manual or the protection provided by the Meter might be impaired.
• Avoid working alone so assistance can be rendered.
• Do not use the Meter in wet or dirty environments.

- Do not use the Meter if it appears damaged. Inspect the Meter before use. Look for cracks or missing plastic. Pay particular attention to the insulation around the connectors.

- Have the Meter serviced only by qualified service personnel.

- Use extreme caution when working around bare conductors or bus bars. Contact with the conductor could result in electric shock.

- Do not hold the Meter anywhere beyond the tactile barrier.

- When measuring current, center the conductor in the clamp.

- Never operate the Meter with the battery cover removed or the case open.

- Never remove the battery cover or open the case of the Meter without first removing the jaws from a live conductor.

- Use caution when working with voltages above 30 V AC rms, 42 V AC peak, or 60 V DC. These voltages pose a shock hazard.

- Do not attempt to measure any voltage that might exceed the maximum range of the Meter.

- Use the proper function for your measurements.

- Do not operate the Meter around explosive gas, vapor, or dust.

- Use only 1.5 V LR44 batteries, properly installed in the Meter case, to power the Meter.

- To avoid false readings that can lead to electrical shock and injury, replace the battery as soon as the low battery indicator (☐) appears. Check Meter operation on a known source before and after use.

- When servicing, use only specified replacement parts.

- Adhere to local and national safety codes. Individual protective equipment must be used to prevent shock and arc blast injury where hazardous live conductors are exposed.

Your shipping carton should include:

1 Clamp meter
2 1.5 V LR44 batteries
1 Carrying case
1 User Manual

If any of these items are damaged or missing, return the complete package to the place of purchase for an exchange.

MEASUREMENTS

Warning

To avoid possible electric shock or personal injury:

• To avoid electric shock or personal injury:
- When measuring current, center the conductor in the clamp.
- Keep fingers behind Tactile Barrier.
- Use the proper function for measurements.

Measuring AC and DC Current

Warning

To avoid electrical shock and injury:

- Do not hold the Meter anywhere beyond the tactile barrier.

- Do not use the Meter to measure currents above the maximum rated frequency (400Hz). Circulating currents may cause the magnetic circuits of the Jaws reach hazardous excessive temperatures.

To measure AC or DC current:

1. Switch on the Meter by pressing ⚙️ button, the default is auto AC/DC A detection mode (AUTO is displayed). Press ≡ button to choose AC A or DC A. The display reflects the chosen function mode.

2. Open the clamp by pressing the jaw release and insert the conductor to be measured into the clamp. Ensure the jaws are firmly closed.

3. Close the clamp and center the conductor using the jaw alignment marks.

4. View the current reading on the display.

Caution

During current measurement keep the jaws away from other current carrying devices such as transformers, motors or energized wires, as they may negatively influence accuracy of the measurement.

If the Meter fails to operate, check battery, test leads, etc., and replace as necessary.

Double check the following:

1. Replace the fuse or battery if the meter does not work.
2. Review the operating instructions for possible mistakes in operating procedure.

Except for the replacement of the battery, repair of the meter should be performed only by a Factory Authorized Service Center or by other qualified instrument service personnel.

The front panel and case can be cleaned with a mild solution of detergent and water. Apply sparingly with a soft cloth and allow to dry completely before using. Do not use aromatic hydrocarbons, gasoline or chlorinated solvents for cleaning.

When battery voltage drops below the value required for proper operation, the battery symbol (☐) appears.

Warning

To avoid shock, injury, or damage to the Meter, disconnect test leads before opening case.

Replacing BATTERY follow below steps:

1. Remove the Meter from measuring circuit.
2. Turn the Meter to OFF position.
3. Remove the screw from the battery cover and open the battery cover
4. Remove the batteries and replace with two 1.5 V batteries (LR44). Observe correct polarity when installing the batteries.
5. Put the battery cover back and re-fasten the screw. Battery: 2 x 1.5 V (LR44)
