WARNING

F. Measuring AC Current (See Figure 8)

To avoid electric shock, never measure current while the test leads are inserted into the input terminals and disconnect test leads and 

tested circuit connections. Never attempt an in-circuit current measurement where the open-circuit voltage between the circuit and the 

ground is greater than 600V. Use proper function and range for any measurements. 

To measure current, do the following:
1. Set the rotary switch to 20A

~

, 200 A

~

 or 600 A

~

2. Press the trigger to open the transformer jaws.
3. Center the conductor within the transformer jaw, then release the Meter slowly until the 

transformer jaw is completely closed, Make sure the conductor to be tested is placed at the 

center of the transformer jaw, otherwise it will cause deviation. The Meter can only measure one 

conductor at a time, to measure more than one conductor at a time will cause deviation.

NOTE:

When current measurement has been completed,disconnect the  

connection between the conductor under test and the jaw, and  

remove the conductor away from the transformer jaw of the Meter.

VII. MAINTENANCE

This section provides basic maintenance information including battery replacement instruction. 

Do not attempt to repair or service your Meter unless you are qualified to do so and have the relevant calibration,  

performance test, and service information. 

To avoid electrical shock or damage to the Meter, do not get water inside the case.

A. General Service
• Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents.
• Clean the terminals with a cotton swab with mild detergent. Dirt and Moisture in the terminals can affect the readings of the Meter.
• Turn the Meter power off when it is not in use.
• Remove the battery when the unit is not in use for a long time. 
• Do not use or store the Meter in a place of humidity, high temperature, explosive, inflammable or strong magnetic field.
