Overload protection: 250 V
Do not measure continuously for more than 15 seconds.

3.6 Continuity test / diode test

FUNCTION
If the measured resistance is less than
50Ω, the buzzer will sound.
The display shows the approximate
voltage drop
Overload protection: 250 V
Do not measure continuously for more than 15 seconds.
3.7 Gain (hFE) of a transistor
FUNCTION
Displays the approx. hFE gain (0-1000) Base current: approx. 10μA -
hFE
4. INSTRUCTIONS
4.1 DC voltage / AC voltage
Warning
TInput voltage max.: 600 V
Do not exceed the specified limits, otherwise there is a risk of electric shock and/or damage
to the device.
• Rotate the turning knob to select the appropriate voltage range.
• Plug the red test probe to the input terminal mAVΩ and the black test probe to the COM
terminal.
• Connect the test probes to the voltage source or the circuit under test.
• Read the measured voltage on the screen.
When measuring a DC voltage, the display shows the polarity of the red test probe.
• The display of the number «1» indicates that the value exceeds the upper limit of the
selected range.
In this case, select a higher range with the rotary knob.
