SAFETY INSTRUCTIONS

In order to avoid electric shock or other injuries, follow the safety instructions below:

1. Before using the device, inspect the case for any mechanical damage. If the case has cracks or is missing any part, do not use the device.
2. Before using the device, check the test leads for any insulation damage. If the test leads has insulation damage or cuts, do not use the device.
3.  Do not input voltages higher than said in the specification.
4. During measurements, do not change the position of the rotary switch.
5. Take extra precaution while measuring voltages above 60 V DC and 30 V AC.
6. Before measurement position the rotary switch to correct position and connect the test leads to the proper terminals.
7. Do not use the device in temperatures exceeding the range in specification, in high humidity, and near explosives and flammables.
8. During measurement, hold the test leads above the finger guards.
9. Before measurement disconnect the measured circuit from power and discharge all capacitors.
10. If the display shows low battery icon, change the batteries. Otherwise the accuracy of measurements may be decreased.
11. Before opening the battery case disconnect the test leads from measured circuit and from the device.
12. Battery must be replaced with a new one and with the same specification (9 V 6LR061 battery).
13. Do not tamper with devices internal circuits. This may lead to measurement decrease or damaging the device.
14. The device is intended for indoors use only.
15. Take out the batteries, if the device is not going to be used for a long time.

OPERATION

AC and DC measurement

1. Connect the red test lead to the VΩ terminal.
2. Connect the black test lead to the COM terminal.
3. Set the rotary switch to proper voltage range.
4. Connect the test leads to a measured circuit.
5. Turn on the circuits power. The voltage and polarization will show on the display.
   *If the range is not known, set the range to highest and gradually lower it, until getting the accurate measurement.

AC and DC current measurement

1. Connect the red test lead to the VΩmA terminal. If the measurement will be in 200 mA – 20 A range, connect the red test lead to the 20 A terminal.
2. Connect the black test lead to the COM terminal.
3. Set the rotary switch to proper current range.
4. Open the measured circuit and connect the test leads in series.
5. The result will appear on the display.

Caution: while connected to the 20 A terminal, measurements can last only 15 seconds in a few seconds intervals.

Resistance measurement

1. Connect the red test lead to the VΩ terminal.
2. Connect the black test lead to the COM terminal.
3. Set the rotary switch to proper Ω range.
4. If the resistance measurement will be conducted on the circuit, disconnect the circuit from power and discharge all capacitors.
5. Connect the test leads to the measured circuit.
6. The result will appear on the display.

Diode measurement

1. Connect the red test lead to the VΩ terminal.
2. Connect the black test lead to the COM terminal.
3. Set the rotary switch to position.
4. Connect the red lead to anode of the diode, and black to the cathode.
5. Voltage drop will be displayed. If the display shows the “1”, it means that the polarization is reversed.

Continuity test

1. Connect the red test lead to the VΩmA terminal.
2. Connect the black test lead to the COM terminal.
3. Set the rotary switch to the position.
4. Connect the test leads to a measured circuit. If the resistance is lower than 30 Ω+20 Ω, the buzzer will buzz.

hFE transistor test

1. Set the rotary switch to the hFE position.
2. Determine the type of transistor (PNP or NPN) and connect the emitter, base and collector to proper sockets.
3. Approximate value of hFE will be displayed.

Capacitance measurement

1. Connect the red test lead to the VΩmA terminal.
2. Connect the black test lead to the COM terminal.
3. Connect the test leads to measured capacitor.
   Caution: before measurement, disconnect the measured circuit and discharge all of the capacitors.

CLEANING AND MAINTENANCE

• The meter will turn off automatically after 15 minutes of idle.
• Clean the device with soft, slightly damp cloth, without abrasive agents.
• To change the battery, unscrew the screw of the battery compartment. Take out the battery compartment cover and replace the battery (note the polarity). Close the battery compartment cover and screw in the screw.
