Frequently Asked Questions - 32-8585 Cotech
How do I measure AC voltage with this multimeter?
Set the rotary switch to the V~ (AC voltage) range. Insert the black probe into the COM jack and the red probe into the VΩmA jack. Connect the probes across the circuit and read the display.
What does 'OL' mean on the display?
OL stands for Overload or Open Loop. It indicates that the measured value exceeds the selected range. Try switching to a higher range or the auto-ranging mode.
How do I replace the battery?
Turn off the multimeter and remove the test leads. Open the battery compartment on the back using a screwdriver. Replace the 9V battery (6F22) with a new one, ensuring correct polarity. Close the compartment and secure the screw.
Can I measure current above 10A?
No, this multimeter is rated for a maximum of 10A (unfused) for short measurements. For currents above 10A, use a clamp meter or a higher-rated instrument. Never exceed the rated limits.
How do I test continuity?
Set the rotary switch to the continuity/diode position (usually marked with a buzzer symbol). Insert the probes as for resistance measurement. If the circuit is connected (resistance < ~30 Ω), the buzzer will sound.
What is the CAT II safety rating?
CAT II means the multimeter is designed for measurements on circuits directly connected to a low-voltage installation (e.g., household outlets). It provides protection against transient overvoltages up to 600V.
How do I use the data hold function?
After taking a measurement, press the 'HOLD' button to freeze the reading on the display. Press it again to release the hold. This is useful for recording readings in difficult positions.
The display shows 'bAt' – what does that mean?
'bAt' indicates a low battery. Replace the 9V battery as soon as possible to ensure accurate measurements and proper operation.
Can I measure capacitance with this multimeter?
Yes, set the rotary switch to the capacitance (often denoted by a capacitor symbol) range. Discharge the capacitor first, then insert the probes (observe polarity if needed) and read the value.
How do I clean the multimeter?
Turn off the device and remove the test leads. Use a soft, dry cloth to wipe the exterior. Do not use any solvents, abrasive cleaners, or immerse the meter in water.
