4. OPERATING INSTRUCTION
4.1 DATA HOLD
If you need data hold when measuring, you can
put on “HOLD”, it will hold the reading; if you put
the button again, data hold will not continue.
4.2 FUNCTION TRANSFORM
Put down the "FUNC" when measuring the current
and voltage. Meter will be transformed between
DC and AC range. Put "FUNC" when measuring
the resistance, capacitance, diode and continuity,
meter will transform among them.
4.3 RANGE TRANSFORM
The auto range is used when measuring the
current, voltage and resistance. Put down the
"RANGE" if the manual range is needed. Each
time you put down, range will go upward; the
minimum range is transformed if "RANGE" is put
down at the maximum range. If the "RANGE" is put
down more than two seconds, auto range is used
again
4.4 HZ/DUTY TRANSFORM
 Put down the "Hz%." when measuring the Hz
range. Meter will be transformed at DUTY range.
