- Page 1 Instruction Manual Digital multimeter Art. 31130...
- Page 2 1. General instructions This instrument complies with CAT. III 600 V overvoltage standards. To get the best service from this instrument, read carefully this user's manual and respect the detailed safety precautions. International symbols used on the multimeter and in this manual are explained in chapter 1.1.3.
- Page 3 - To avoid damages to the instrument, do not exceed the maximum limits of the input values shown in the technical specification tables. - When the multimeter is linked to measurement circuits, do not touch unused terminals. - Caution when working with voltages above 60 V DC or 30 V AC rms. Such voltages pose a shock hazard. - When using the probes, keep your fingers behind the finger guards.
- Page 4 AC or DC Earth ground Double insulated Fuse Conforms to European Union directives 1.1.4 Instructions - Remove test leads from the multimeter before opening the multimeter case or battery cover. - When servicing the multimeter, use only specified replacement parts. - Before opening up the instrument, always disconnect from all sources of electric current and make sure you are not charged with static electricity, which may destroy internal components.

A mA µA Disables automatic power-off feature. Power-up Option Press it to enter and exit the Data Hold mode. HOLD/ Any switch Press it and hold 2 seconds, backlight on;...
- Page 7 To enter and exit the manual range mode: 1. Press RANGE key. The multimeter enters the manual ranging mode. AUTO turns off. Each presses of RANGE key increments the range. When the highest range is reached, the multimeter wraps to the lowest range.
- Page 8 3.2.2 Resistance measurement To avoid electrical shock and/or damage to the instrument, disconnect circuit power and discharge all high-voltage capacitors before measuring resistance. The multimeter's resistance ranges are 400.0 , 4.000 k , 40.00 k , 400.0 k , 4.000 M and 40.00 M .
- Page 9 Note: Continuity test is available to check open/short of the circuit. 3.2.5 Capacitance measurement To avoid electrical shock and/or damage to the instrument, disconnect circuit power and discharge all high-voltage capacitors before measuring capacitance. Use the DC voltage function to confirm that the capacitor is discharged. The multimeter's capacitance ranges are 50.00 nF, 500.0 nF, 5.000 µF, 50.00 µF and 100.0 µF.
- Page 10 2. Insert ‘K’ type thermocouples into the COM terminal and C terminal (or you can insert it by using Multi Function Socket), takings care to observe the correct polarity. 3. Touch the object with the thermocouple probe for measurement. 4. Read the stable reading from LCD 3.2.8 Current measurement To avoid damage to the multimeter or injury if the fuse blows, never attempt an in-circuit current measurement where the open-circuit potential to earth is greater than 250 V.
