Measuring AC voltage
The maximum input voltage in the AC-V range is 600 V RMS. To prevent dangers through
electric shocks and/or damage to the appliance, do not take measurements of voltages of more
than 600 V RMS.
Set the function switch to range "V"
To select the "AC", press the button "SEL".
Insert the black and red test leads into the inputs COM and INPUT.
Apply the test leads to the circuit to be measured and read the value.
Measuring resistance / continuity / diode
Before carrying out each resistance measurement, make sure that the circuit to be measured is
not energized and that all condensers are deenergized.
Set the function switch to range "Ω/ ".
Press the "SEL" button to switch between measuring the resistance, continuity and diode.
Insert the black and red test leads into the inputs COM and INPUT.
Apply the test leads to the circuit to be measured and read the value.
Note: The continuity test is suitable to determine if there are short circuits / open circuits.
Auto Power OFF
In order to save the battery, the appliance automatically switches off after approx. 30 minutes.
If the appliance is in the "sleep mode", it can be returned to normal measuring mode by pressing
the "SEL" button.
True RMS
If measuring non-sinus wave forms, low measurement errors can occur if using the True RMS
function, in comparison to using traditional measurement procedures.
Sinus-form and non-sinus form signals can be accurately measured using the True RMS function.
With AC and AC voltage, zero compensation fluctuations of
1 – 50 Digits can occur.
However, the test result is not influenced.
In order to maximize the precision of the appliance, the AC voltage should be > 13 mV and the
AC > 1.3 A.
