2. Set the range switch at the desired V-range position.
3. Connect the test leads with the source or load under measurement.
4. Read the measured value from the LCD. The polarity of the red lead connection is also indicated.
REMARKS
•
The LCD displays the overrange indication “1” if the measured value is too high for the range you are using.
Select a higher range.
•
Place the range selector in the highest position if the value to be measured is unknown beforehand.
5.7. Measuring
AC
Voltage
WARNING
The input voltage should not exceed 700Vrms AC. Be very careful and avoid electroshocks when working with high
voltages.
1. Connect the black test lead with the COM jack and the red test lead with the V jack.
2. Set the range switch at the desired V-range position.
3. Press the DC/AC button to install the AC measuring mode.
4. Connect the test leads with the source or load under measurement.
5. Read the value from the LCD.
REMARKS
•
The LCD displays the overrange indication “1” if the measured value is too high for the range you are using.
Select a higher range.
•
Place the range selector in the highest position if the value to be measured is unknown beforehand.
5.8. Measuring
DC
Current
WARNING
Deactivate the circuit to be tested before connecting it to the meter.
1. Connect the black test lead with the COM jack and the red test lead with the A jack for current measurements up
to 200mA. Move the red lead to the 10A jack for measurements up to 10A.
2. Select the desired A-range with the range switch.
3. Connect the test leads in series with the load under measurement.
4. Read the measured value from the LCD. The measured voltage value and the polarity of the red connection are
displayed.
REMARKS
•
The LCD displays the overrange indication “1” if the measured value is too high for the range you are using.
Select a higher range.
•
Place the range selector in the highest position if the value to be measured is unknown beforehand.
•
Respect the limit values
: the max. current for socket A is 200mA, the max. current for the 10A socket is 10A.
The fuse will blow if the limit values are exceeded.
