3.11 VlowZ
The Vlow Z position measures AC voltage with lower impedance (500kΩ) than
normal voltage measurement, this function is used to avoid measuring ghost voltages.
4. MAINTENANCE
The instrument has no parts that can be replaced by personnel who are not trained
and approved. Any non-approved repair or other work, or replacement of a part by
an "equivalent", may severely compromise safety
4.1 Cleaning
Periodically wipe the case with a damp cloth and mild detergent. Do not use
abrasives or solvents. Dirt or moisture in the terminals can affect the readings. Dry the

signals before replacing the fuses.
1. Turn the rotary switch to position and toggle the
yellow key.
2. Plug a test lead into the + terminal and touch the probe to
the A or mA/μA according to the fuse to be tested
A good A terminal fuse is indicated 000.0Ω to 000.2Ω.
3. If the display reads OL, replace the fuse and test again
4. If the display shows any other value, have the meter
serviced.

4.3 Replacing the batteries and fuses

To avoid false readings, which could lead to possible electric
shock, or personal injury, replace the batteries with LR6
batteries as soon as the battery indicator appears.
To prevent damage of injury, install ONLY replacement fuses with the specified
amperage, voltage, and interrupt ratings.
Disconnect test leads before opening the battery door.
