Frequently Asked Questions - 5125 PeakTech
How do I switch between AC and DC voltage measurements?
Press the FUNC button to toggle between AC and DC modes. The display will show the corresponding symbol.
What does the 'OL' reading mean?
OL (Over Load) indicates the measured value exceeds the selected range. Try a higher measurement range or use auto range.
How to replace the battery?
Remove the screw on the back cover, lift off the cover, replace the 9V battery with a new one (6F22 or NEDA 1604), and secure the cover.
Is the multimeter suitable for measuring mains voltage?
Yes, the PeakTech 5125 has a CAT II 600V rating, suitable for measuring household mains voltage. Always follow safety precautions.
What is the maximum current I can measure?
The maximum current is 10 A (AC or DC). For currents above 2 A, limit measurement time to 10 seconds and allow 15 minutes cooldown.
How do I use the capacitance measurement?
Set the rotary switch to the capacitance position (usually marked with a capacitor symbol). Insert the component into the dedicated socket or use test leads, ensuring it is fully discharged.
What does the 'Hold' button do?
The Hold button freezes the current reading on the display. Press again to release.
Can I measure frequency with this device?
Yes, set the dial to Hz or press the Hz button in voltage mode. The frequency range is up to 10 MHz.
How to clean the multimeter?
Disconnect test leads and power off. Wipe the exterior with a damp cloth and mild detergent. Do not use abrasives or solvents.
Why does the multimeter beep continuously?
Continuous beeping in continuity mode indicates a short circuit (resistance below ~30 Ω). Check your test leads or circuit.
