General Maintenance

This section provides basic information on maintaining 
the meter, such as replacing fuses and the battery. Only 
experienced and authorized personnel should make 
repairs to the meter.

Warning

To avoid injury or damage to the meter,do not allow
moisture inside the case and remove test leads 
before opening battery cover.

• Use a damp cloth to regularly clean the outside of the 
  meter.  Do not use abrasives or chemical solvents.Dirty 
  or damp input jack can adversely affect readings.
• To clean input jacks, follow the following steps:
1.Turn off the instrument and remove the test leads.
2.Clear any dirt or other particles on the input jacks.
3.Use a cotton ball/swab with a lubricant (i.e. WD-40) to 
   clean off the contacts of the input jacks.
4.Use a separate cotton ball/swab for each jack to 
   prevent cross-contamination.

Note:

• Even if the indicator doesn’t go off, voltage may still 
  exist.Do not use NCV detection as the sole 
  determination of a lack of voltage present in a 
  conductor.Detection could be impaired by socket 
  design, insulation, etc.
• When measuring voltage through input jacks, NCV 
  indicator may light up due to induced voltage.
• External environmental interference could cause false 
  NCV indications.

Replacing the Battery and Fuses

5.3

 

Replacing the Probe

1. Under normal conditions, it is unnecessary to replace the fuse. 
    Don't replace it until the probes are unplugged and the power is 
    shut down. Take out the two screws of the rear cover to remove 
    the housing.
2. The specification of the fuse is:
    F1 F 10A H 600V, F2 F 400mA H 600V
    The replacement should be of the same specification.
3. The battery for this multimeter is 9V NEDA 1604 or 6F22. 
    The replacement should be of the same specification.
4. Don't put the instrument into use until the rear cover is screwed 
    after replacing battery or fuse.

To avoid electric shock, make sure the probes are disconnected 
from the measured circuit before removing the rear cover.
Make sure the rear cover is tightly screwed before using the 
instrument.

       Warning

If insulation on probe is damaged, replace it.

Use meet EN 61010-031 standard, rated CAT III 600V, 10A or better probe.

       WARNING
