SAFETY INFORMATION

The meters comply with:

IEC/EN 61010-1 3rd Edition Pollution Degree 2, Measurement Category IV 600V and Measurement Category III 1000V

IEC/EN 61010-2-31 for test leads

EMC IEC/EN 61326-1

Measurement Category IV (CAT IV) is for measurements performed at the source of the low-voltage installation. Examples are electricity meters and measurements on primary overcurrent protection devices and ripple control units.

Measurement Category III (CAT III) is for measurements performed in the building installation. Examples are measurements on distribution boards,

circuit-breakers, wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed installation, and equipment for industrial use and some other equipment, for example, stationary motors with permanent connection to the fixed installation.

⚠️ WARNING: Read before using

• To avoid possible electrical shock or personal injury, follow these instructions and use the Meter only as specified in this manual.
• Do not use the Meter or test leads if they appear damaged, or if the Meter is not operating properly. If in doubt, have the Meter serviced.
  • Always use the proper function and range for measurements.
• Before rotating the function range selection switch, disconnect test probe from circuit under test.
• Verify the Meter's operation by measuring on a known voltage source.
• Do not apply more than the rated voltage, as marked on the Meter, between the test probe or between any test probe and earth ground.
• Use the Meter with caution for voltages above 30 V ac rms, 42 V ac peak, or 60 Vdc. These voltages pose electrical shock hazards.
• Disconnect circuit power and discharge all high-voltage capacitors before testing resistance.
• Do not use the Meter around explosive gas or vapor.
• When using the test leads, keep your fingers behind the finger guards.

MAINTENANCE AND REPAIR

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.

Quick check on 0.5A FUSE:

Step 1: Turn the rotary switch to mA position.

Step 2: Use a multimeter with continuity function to verify the fuse continuity for the fuse of mA/ A terminal. Connect the test leads to mA/ A terminal and COM terminal.

Continuity buzzer activates: the fuse is OK

Continuity buzzer is not activated: the fuse is burnt. Replace the fuse as specified.

Step 1: Turn the rotary switch to A position.

Step 2: Use a multimeter with continuity function to verify the fuse continuity for the fuse of 10A terminal. Connect the test leads to 10A terminal and COM terminal.

A
·))	-	OK
·)	-	OK

Continuity buzzer activates: the fuse is OK

Continuity buzzer is not activated: the fuse is burnt. Replace the fuse as specified.

F2 11A H 1000V fast-fuse, (Φ10×38)mm

Except for the replacement of the battery, repair of the meter should be performed only by an 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.

WARNING

To avoid shock, injury, or damage to the Meter:

Disconnect test leads before opening case.

Use ONLY fuses with the amperage, interrupt, voltage, and speed ratings specified.

Replacing BATTERY follow below steps:

1. Disconnect the test lead probe from measuring circuit.
2. Turn the Meter to OFF position.
3. Remove the screws from the battery cover and open the battery cover
4. Remove the batteries and replace with one 9V (6F22) or equivalent. The battery cover provides the correct polarity fitting construction design. Install the battery in the battery cover.
5. Put the battery cover back and re-fasten the screw.

Battery: 9V (6F22) Battery or equivalent

Replacing FUSE follow below steps:

1. Disconnect the test lead probe from measuring circuit.
2. Turn the Meter to OFF position.
3. Remove the screws from the enclosure and open the enclosure.
4. Remove the broken fuse and replace with new specified fuse.
5. Put the enclosure back and re-fasten the screw.
