Input sensitivity: 1.5V;
Overload protection: DC or AC 250V peak value.
Open circuit voltage: 400mV;
Open circuit protection: DC or AC250V peak value.
Note: When the range of 400 Ω is used, users shall firstly make the multimeter probes in short circuit state,
obtain the resistance of the down-lead, and then reduce it from the actually measured value.

Range Displayed value Test conditions
Voltage drop in forward direction of diode The DC current is around 0.5mA in forward direction,
and around 1.5V in backward direction.
The buzzer rings for long time, and the
resistance between two tested points is
smaller than 40±30
Ω .
Open-circuit voltage is around 0.5V.
Overload protection: DC or AC250V peak value.
Warning: It’s forbidden to input voltage value in this range for the sake of safety!

IV. Application Method
4-1 Description of operating panel (as shown in Figure 1)
1. LCD unit: It displays the numerical value measured with the instrument and its unit;
2. Functional switches
2-1 “HzDUTY” key: AC/DC current and voltage DC/AC. This key may be pressed
for conversion into AC current if DC current is measured, or for conversion of
frequency and duty ratio (1-99% ) if frequency is measured.
2-2 Voltage, current and capacitance level key: After this functional switch is pressed,
the reading will be zeroed, and the product will step into the measurement of relative
value, and the display unit will show the sign “REL”; and after this key is pressed once
more, the product will exit from the measurement of relative value;
