INSERTING THE BATTERIES6.
Replace the batteries once the battery replacement symbol is displayed.1.
Remove the two screws from the battery compartment with a Phillips screwdriver and take off the cover of the 2.
battery compartment.
Insert two LR44 button-cell batteries into the battery compartment. Make sure the polarity is correct (‘+’ = positive). 3.
The button cell’s positive terminal has to face upwards.
Close the battery compartment.4.
An operating voltage of ca. 2.4 V will make the battery replacement symbol appear on the display. When
this occurs, you should change the batteries.
OPERATION7.
Disconnect the tester from the test circuit before changing the measurement function. Before •
measuring, disconnect the measuring objects from any voltage source and discharge all
capacitors. Do not touch the test prods during operation.
Never exceed the max. input values, as any damage to the measuring instrument could put •
users in danger!
Only use the test prods included in delivery.•
Carefully remove the protective cap from the device.1.
Press and hold the ‘FUNC.’ button for around one second to turn the device on.2.
The device automatically switches into ‘SCAN’ mode. The display shows ‘- - - -‘ in the centre and ‘SCAN’ on the 3.
upper left corner. In this mode, the device selects the suitable value range automatically.
Alternatively, you can manually select the desired measuring function (resistance, continuity, diode, capacitance) by 4.
pressing the ‘FUNC.’ button. Each press switches to the next measuring function.
The appropriate value range for all measurement modes is selected automatically.
By pressing the ‘RANGE’ button you can manually set the value range and the decimal places for capacitance and 5.
resistance measurements.
Turn the thumb wheel between the test prods to adjust the distance between the test prods to meet your 6.
requirements.
Press and hold the ‘FUNC.’ button for around two seconds to turn the device off and thus conserve
battery power. The device turns itself off after a ten-minute period of inactivity.
Measuring resistance
When in the ‘SCAN’ mode, press the ‘FUNC.’ button once. ’O.L’ appears in the centre of the display, and on the 1.
bottom right the display shows ‘M Ω’.
If required, press the ’RANGE’ button to set decimal places and to switch between MΩ, KΩ and Ω .2.
Touch the measuring points with the test prods. The display shows the measuring value.3.
If the measured resistance is greater than 1 MΩ, it will take some time for the device’s measurement •
value display to stabilise.
If there is an overrange (i.e. with an open measuring circuit) the display will show ‘O.L’.•
When in ‘SCAN’ mode, measurements ≥ 60.00 MΩ cannot be made. In such a case, manually switch •
to the ‘Measure resistance’ mode.
Measuring continuity
When in the ‘SCAN’ mode, press the ‘FUNC.’ button twice. ’OL.’ is displayed in the centre, on the bottom right ‘Ω, 1.
and at the top of the display the continuity symbol appears.
Touch the measuring points with the test prods. The display shows the measuring value.2.
If the resistance is lower than 30 Ω, a signal sounds.3.
Testing diodes
When in the ‘SCAN’ mode, press the ‘FUNC.’ button three times. ‘OL’ appears in the centre of the display, and on 1.
the top right of the display the diode symbol is shown, with ‘V’ below it.
Connect the tester’s + test prod to the diode and the - test prod to the cathode (the diode’s cathode is usually marked 2.
by a coloured ring or dot).
When testing a functioning diode in forward bias, a voltage of between around 0.25 V (germanium) and/or 0.7 to 3.
2.0 V (silicium) is measured.
To test the diode in reverse bias, change the test prods’ position so that the + test prod is connected to the cathode 4.
and the – test prod to the anode.
The diode is ne if ‘O.L’ is displayed. If, however, a voltage value is displayed, the component to be
measured is either wrongly connected or out of order.
Measuring capacitance of capacitors
When in the ‘SCAN’ mode, press the ‘FUNC.’ button four times. ’0.000’ appears in the centre of the display, and 1.
on the right ‘n F’.
Short the test prods before starting to measure.2.
Contact the measuring points with the test prods. The display shows the measuring value.3.
When measuring high capacitance, it will take some time for the measuring value display to •
stabilise.
When in ‘SCAN’ mode, measurements ≥ 6,000 mF cannot be made. In such a case, manually switch •
to the ‘Measuring capacitance of capacitors’ mode.
Measuring voltage
Make sure the device is turned off. Carefully remove the resistance/continuity/diode/capacitance test prods from the 1.
tester.
Insert the plug of the voltage test prods into the tester’s connector, observing the correct polarity. Observe the connector’s 2.
and the plug’s respective +/- markings.
Switch the device on.3.
The device automatically switches into ‘SCAN’ mode. In this mode, the device automatically detects whether AC or DC 4.
voltage is connected. Moreover, the tting value range (V or mV) will be determined.
Alternatively, you can set the voltage type manually by pressing the ‘FUNC.’ button.5.
When in the ‘SCAN’ mode, press the ‘FUNC.’ button once to measure AC voltage. ’AC’ is displayed on the left side.6.
Press the ‘FUNC.’ button once more to measure DC voltage. ’DC’ is displayed on the left side.7.
When outside the ‘SCAN’ mode, you can freely set the decimal places and switch between V and •
mV by using the ‘RANGE’ button.
Press and hold the ’RANGE’ button for two seconds to revert to automatic selection of the value •
range within the selected mode.
From a voltage of • ≥ 30 V AC/DC the bolt symbol is displayed, which stands for high voltage.
Take the protective caps off the test prods and short the test prods.8.
Connect the test prods to the object to be measured. The connected voltage is displayed.9.
CARE AND MAINTENANCE8.
Disconnect the tester from the test measuring points and turn it off.•
Wipe the housing surface with a clean, soft and dry cloth or, if heavily soiled, with a slightly dampened cloth.•
Do not use aggressive detergents or chemical solvents. They could damage the housing.•
Do not apply pressure on the display. It could be damaged or scratched.•
Make sure the device is completely dry before it is operated again.•
