Mastering the Art of Soldering
value is more than 1 MΩ, the reading takes a few seconds to stabilize, which in high
resistance mode is normal.
2. When the input is open, the overload condition is displayed.
3. When measuring the on-line resistance, make sure that all the power of the circuit under
test are turned off and all the capacitors are fully discharged.
4. Do not input voltage in the resistance range.
Diode test
1. Insert the black probe to "COM" and the red probe to "V/Ω"
(note that the polarity of the
red probe is "+");
2. Put the range switch to " ". Connect the black probe to the cathode and the red
probe to the anode. On the display will be shown the approximative forward voltage drop.
Non-contact voltage detection (with NCV instruments)
1. Set the function range switch to the NCV range position.
2. Close the instrument to > 100 VAC
3. When the instrument distance < 30 mm, the instrument within the non-contact voltage
detection alarm will start to beep.
Data retention function
Press the (right) key, then the measurement data will be locked, and will be easy to read and
record. Then press the right button to reset the instrument to restore the measurement.
Back-light display
Press the "left" button and the back-light will be turned on for about 10 seconds.
Instrument maintenance
This instrument is a precision instrument, the user should not arbitrarily change the circuit.
Note
:
1. Do not connect voltages above 500 VDC or 500 Vrms;
2. Do not measure the voltage value
when the range switch is in resistance mode "Ω";
3. Do not use the multimeter for testing when the battery is not installed or the back cover is
not installed;
4. Before replacing the battery of fuse, remove the test leads from the test point and turn off
the power switch.
Fuse replacement
When replacing the fuse, use the same fuse as the model type.
