 Connect the alligator clip to the circuit to be measured 

and the measurement probe too.

③

 Read the display.

Note:

•  MΩ measurement button is not available.

•

1. The followings are important to safety. Read this 

manual throughly to maintain the instrument.

2. Calibrate and inspect the instrument at least once a 

year to ensure safety and maintain its accuracy.

1. Do not open the battery door with live input terminals 

to avoid electric shock.

2. Make sure the power is OFF, before starting the 

replacement.

[6] MAINTENANCE

WARNING

6-1 Simple Examination

1) Appearance:

• 

Check that the instrument does not look damaged 

caused by dropping etc.

2) Measurement Probe, Alligator Clip, Earth lead:

• 

Check that the measurement probe and the alligator clip 

fit on the instrument.

• 

Check for the earth lead especially exposed core wire 

anywhere on it.

If you find any problem on the above items, stop using 

immediately and ask us to repair it.

6-2 Calibration

For requesting calibration and inspection, contact an 

authorized agent/distribution service provider, listed in our 

website. (See 7-2 section 4)

6-3 Battery Replacement

WARNING

Pre-installed battery

Since the pre-installed battery is for monitoring, it may not 

be durable as typically expected.

*The purpose of the battery for monitoring is to check for 

the functions and performances of the product.
