Frequently Asked Questions - LSG4 VOLTCRAFT
How to use the HOLD function?
Press the HOLD button (9) to freeze the displayed value. A beep confirms activation and the screen shows 'HOLD'. Press again to deactivate or change the measurement function.
How to replace the multimeter batteries?
Turn off the device and remove the test leads. Remove the rubber holster (12), unscrew the battery compartment (11) and insert two new AAA batteries with correct polarity. Close carefully.
What does the display 'OL' mean?
'OL' (OverLoad) indicates that the measurement range is exceeded or the circuit is open. Check the selected function and reduce the range if necessary.
How to test a diode?
Set the multimeter to diode test position (diode symbol). Connect the red lead to the V/Ω socket and black to COM. Connect the probes to the diode: the forward voltage (UF) is displayed. If 'OL' appears, reverse the probes.
How to perform a cable search?
Activate the signal generator by pressing the 'Tone' button (3). Connect the alligator clips to the de-energized cable. Turn on the receiver (20) and approach the tip (21) to the cable. Use button (19) to activate the speaker or connect headphones.
What is the maximum measurable voltage?
In multimeter mode, the maximum voltage is 600 V in CAT III (DC or AC RMS). For the cable detector, do not exceed 75 V DC or 50 V AC.
How to use the MAX function?
In voltage measurement mode (V), press the MAX button (10). 'MAX' is displayed and the maximum value is recorded. Press again to return to normal mode.
How to clean the device?
Use a clean, lint-free, slightly damp cloth. Do not use solvents or sharp objects. Let dry completely before reuse.
What to do if the device does not turn on?
Check the battery condition: replace if necessary. Make sure the rotary switch (4) is not set to 'OFF'. If the problem persists, consult a technician.
How to test a telephone line?
Connect the alligator clips (red to Lb, black to La) or the modular connector (15) to the socket. The L1 display (1) lights up green if polarity is correct, red if reversed, and flashes during an incoming call.
