 Read First
-Avoid working alone so assistance can
be rendered.
- Do not use test leads or the Tester if
they look damaged.
- Do not use the Tester if the Tester is
not operating properly or if it is wet.
- Use the Tester only as specified in the
Instruction card or the protection by
the Tester might be impaired.
- Use extreme caution when working
around bare conductors or bus bar.
Contact with the conductor could result
in electric shock.

 Caution
Take sufficient care to not to apply shock,
vibration or excessive force to the jaw tips.

Data Hold
Data Hold Beep Guard
The internal sounder will beep continuously
with the LCD display flashing in the Data
Hold mode when the measured signal is
larger 50 counts than the LCD reading.
Peak Hold
(forcing into the manual range mode)
Low Pass Filter
(forcing into the manual range mode)
•The Cut-Off frequency of the low pass
filter is about 100Hz with attenuation
characteristic of approx. –24dB/octave.
Auto Range / Manual Range
Comparator
•The Meter offers 3 limit values (0.25mA,
0.5mA and 3.5mA) in accordance with
safety standards. (EN 60950-1)
•The internal sounder will beep continu-
ously with the LCD display flashing
when measured value exceeds the
confirmed limit value.
