User Manual

Note: In 20 Ω-range, effective reading must be over 20 counts.
Remark:
1. Q value is the reciprocal of DF.
2. The specification is based on the testing socket (clips)
performed on the meter.
3. L (C) x indicates the reading of inductance (capacitance) on the
display.
e. g.: inductance (capacitance) = 18.888 (F) then L (C) x
= 18888.
4. In 20 Ω-range, effective reading must be over 20 counts.
4. Operation Instruction
Caution!
It is recommended, that you read the safety and operating
instructions before using the meter.
Warning!
Before taking any measurements, please isolate the UDT from the
power supply. To avoid electric shock, plug off the test leads from
the meter before opening case and battery hatch. Do not use the
meter if test leads, alligator clips and appearance look cracked and
damaged. Please check periodically. To avoid electric shock,
discharge the circuits completely, before taking any measurements.
Caution!
When it appears to have abnormal situations, such as you can not
turn on the meter to operate.
1. It is normal situation, when you can not turn on the meter after
turning off the meter just for few seconds. Please wait a
moment to turn it on again.
2. When you can not operate the meter normally, please turn off it
and restart the meter.
3. There are two measuring concerns when it comes to measure
under 0,5 Ohms.
a) Use tidy alligator clip the DUT (Device Under Test)
reliably. Before taking any measurements, please make
short-zeroing calibration to make sure impedance
between test leads.
b) The DUT (Device Under Test) must keep clean
andshouldn´t have any oxidization existed or untidy
phenomenon, which will affect accuracy.
