1. 1. 1. INTRODUCTION

INTRODUCTION INTRODUCTION
The instrument is a high performance, high accuracy, 3
high LCD multi-meter for measuring DC and AC voltage, DC and AC current,
Resistance and Capacitance, Frequency, temperature, duty circle, Transistor, Diode
and Continuity test. Design parameter: unit indication, data hold (HOLD), relatively
measuring (REL), AUTO/MANUAL range, auto off and buzzer sounds, etc.
The Dual-slop A/D converter CMOS technology for auto-zero, polarity
selection and over-range indication. Full overload protection is provided. Because
of its outstanding features, it is most suitable for use on production lines or for lab,
R & D, maintenance and repair work.

1. Check the 1.5-volt battery by setting the ROTARY Switch removes to OFF position.
If the battery is weak, a sign will appear on the display. If this does not appear on
the display, proceed as below. See MAINTENANCE if the battery has to be replaced.
2. The mark, or sign next to the lead jacks, is for warning that the input voltage or
current should not exceed the indicated values.
This is to prevent from damaging the internal circuits.
3. The function switch should be set to the range that you want to test before operation.

1) Insert the BLACK test lead to "COM" jack and RED test lead to the "V/Ω/Hz"
jack.
2) Set the FUNCTION switch to " " range.
3) The default range is Auto range, and "AUTO" is displayed. Pressing RANGE key
switch to manual range, 400mV/4V/40V/400V/1000V can be selected.
4) Connect the test leads to the tested point, the voltage and polarity which connected
with the red lead will appear on LCD.
Note: Note: Note:
1) Manual range, if LCD display "OL", over range is being indicated and the
FUNCTION switch must be set to a higher range.
2) Do not measure over 1000V, or, the meter will be damaged.
3)Caution to avoid contact with high voltage circuits when measuring high voltage.
