OPERATING INSTRUCTIONS

Attention before operation

Check battery. When the battery voltage drop below proper operation range, the “ ” symbol will appear on the LCD display and the battery need to changed.
Pay attention to the “ ” besides the input jack which shows that the input voltage should be within the specified value.
The toggle switch should be positioned to desired range for measurement before operation.

Measuring DC & AC Voltage

Set the toggle switch at the desired “ ” range position, it shows symbol for testing DC voltage, if you want to test AC voltage, push “SELECT” button switch.
Connect test leads across the source or load under measurement.
You can get reading from LCD. The polarity of the red lead connection will be indicated along with the DC voltage value.

NOTE:

1. “ ” means you can’t input the voltage more than 600V, it’s possible to show higher voltage, but it may destroy the inner circuit or pose a shock.
2. Be cautious against shock when measuring high Voltage.

Measuring Resistance

1. Set the toggle switch at the desired “ ” range position.
2. Connect test leads across the resistance under measurement.
3. You can get reading from LCD.

NOTE: Max. input overload: 600V rms＜10sec

1. For measuring resistance above 1MΩ, the mete may take a few seconds to get stable reading.
2. When the input is not connected, i.e. at open circuit, the figure ‘OL’ will be displayed for the over-range condition.
3. When checking in-circuit resistance, be sure the circuit under test has all power removed and that all capacitors have been discharged fully.

Measuring Capacitance

Set the toggle switch at the desired “ ” range position, push “SELECT” to choose Capacitance measurement.
Connect test leads across the capacitance under measurement.
You can get reading from LCD.
NOTE: Max. input overload: 600V rms＜10sec

1. Capacitors should be discharged before being tested.
2. When testing large capacitance, it will take longer time before the final indication ( For 100uF~60mF range, it will take about 10 seconds ).
3. When testing small capacitance (≤1uF), to assure the measurement accuracy, first press “REL”, then go on measuring.

Diode & Audible continuity Testing

1. Set the toggle switch at the “ ” range position, push “SELECT” to choose Diode or Aud i ble continuity measurement.
2. On diode range, connect the test leads across the diode under measurement, display shows the approx. forward voltage of this diode.
3. On Audible continuity range, connect the test leads to two point of circuit, if the resistance is lower than approx. 50Ω, the buzzer sounds.

NOTE: Make sure the power is cut off and all capacitors need to be discharged under this measurement.

Battery replacement

1. When the battery voltage drop below proper operation range the ” ” symbol will appear on the LCD display and the battery need to changed.
2. Before changing the battery, set the toggle switch to “OFF” position. Open the battery cover by rotary the battery cover.
3. Replace the old battery with the same type battery (AAA R03P 1.5V×2).
4. Close the battery cover and rotary the battery cover to lock it.

Maintenance

1. Use only moist fabric or small amount of detergent but not chemical solution for cleaning.
2. Do not use the meter before the back cover is properly closed and screw secured. Upon any abnormality, stop operation immediately and send the meter for maintenance.
3. Please take out the battery when not using for a long time.
