 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.
- Do not use the Tester to measure volt-
ages in circuits that could be damaged
by the Tester’s low input impedance
(approximate 4KΩ)
- Use caution with voltages above 30 V
ac rms, or 60 V dc. These voltages
pose a shock hazard.
Symbols as marked on the Tester
and Instruction card
 Safety Information
To ensure safe operation and service of
the Tester, follow these instructions.
Failure to observe warnings can result in
severe injury or death.

when powering up. Please replace the
battery when 0% is shown.
 Caution
The Tester powers up in Ω/ continuity
mode.
Self-Testing Aid
ACA
• Do not measure while powering up, it
will cause Self-Testing failure.

 Warning
Do not apply more than 1000VDC / 750
VAC between Tester terminal and earth
ground.
 Caution
When connecting the test leads to the
circuit or device, connect the black lead
before the red lead ; when removing the
test leads, remove the red lead before
the black lead.
Resistance / Diode
Priority of function
The LCD display shows
voltage mode when the
input Terminal is
satisfied by the following
conditions:
ACV 1.3V ~ 999.9V
DCV 2.1V ~ 999.9V
-0.7V ~ -999.9V
The LCD display shows
Ωmode when the input
terminal is satisfied by
the following conditions:
0 ~ ∞Ω
ACV 0 ~ 0.9V
DCV -0.4 ~ -0.2V
DCV 1.0 ~ 2.0V
The LCD display shows
diode mode when the
Input Terminal is satis-
fied by the following
conditions:
DCV 0.4 ~ 0.8V
The LCD display shows
AC mode when the
Current Input Jaw is
satisfied by the following
conditions :
ACA 0.9A ~ 600.0A
Data Hold
Data Hold is not available when “OL KΩ“
is displayed with no input signals.
Auto Hold ( ACA only )
Data Hold Beep Guard
The internal sounder will beep continu-
ously with LCD display flashing in two
situations in the Data Hold mode:
1. The Meter measures a signal different
from the LCD reading.
2. The measured signal is the same unit
as the LCD reading and is larger 50
counts than the LCD reading.
Auto Power Off

Battery Replacement
Caution
The calibration seal can only be
punctured by certified distributor for
annual calibration otherwise the meter’s
performance can not be warranted.
