OPERATION

This instrument has been designed and tested in accordance with IEC Publication 1010, Safety Requirements for Electronic
Measuring Apparatus, and has been supplied in a safe condition. This instruction manual contains some information and warning which have to be followed by the user to ensure safe operation and to retain the instrument in safe condition.

3-1 Preparation and Caution before Measurement.

1. Before measurement, warm up for at least 60 seconds.
2. When the function switch selector is changed during measurement, be sure do so only after removing the test leads from the equipment.
3. If the equipment is used near noise generating equipment, be aware that display may become unstable or indicate large errors.
4. Maximum rated voltage to earth for voltage measurements terminals is 600V AC/DC CAT. II.

3-2 Voltage Measurements

1. Connect the red test probe to the “V-S ” input terminal and the other (black) test lead to the ” COM “, terminal.
2. Set the function switch to 、 position.
3. Push the blue key to the ACV or DCV function.
4. Connect the test probe and lead to the device to be measured.

WARNING
TO AVOID ELECTRICAL SHOCK, HAZARD OR DAMAGE TO METER, DO NOT ATTEMPT TO MEASURE VOLTAGE THAT MIGHT EXCEED 600 VOLT DC OR 600 VOLT AC. DO NOT APPLY MORE  THAN 600 DC OR AC RMS BETWEEN THE COMMON INPUT TERMINAL AND EARTH GROUND.

NOTICE
UNSTABLE DISPLAY MAY OCCUR ESPECIALLY AT 4.2V RANGE, EVEN THOUGH YOU DON’T PUT TESTED LEADS INTO INPUT TERMINALS. IN THIS CASE, IF AN ERRONEOUS READING IS SUSPECTED, SHORT THE ” V-Ω ” TERMINAL AND THE ” COM ” TERMINAL, AND MAKE SURE THE ZERO DISPLAY.

3-3 Adaptor (Transducer) measurements

1. Set the function switch to 、 position and push blue key 2 seconds to enter the transducer function measurements. Push blue key to select approximate function with the adaptor head.
2. Connect the adaptor head with the DMM.
3. Use the adaptor to measire the unknown quantity.

3-4 Resistance Measurement

1. Connect the red test probe to the V-Ω terminal and the other (black) test lead to the ” COM “, terminal.
2. Set the function switch to Ω position and push the blue key to select resistance function.
3. For correct reading, ensure that the device being tested contains no voltage.
4. Connect the test leads across the resistor to be measured. In order to ensure the best accuracy in measurement of low resistance, short the test leads before measurement and memory the test probe resistance in mind. This necessary to subtract for the resistance of the test leads themselves

3-5 Continuity Check by Buzzer

1. Connect the red test probe to the ” V-Ω ” terminal and the other black test lead to the ” COM ” terminal.
2. Set the function switch to ” Ω ” position and push the blue key to select continuity function.
3. Connect the test probe and lead to the circuit to be measured. The buzzer will sound if the resistance of the circuit measured is lower than 50Ω.

3-6 Diode Check

1. Set the function switch at ” Ω “ position, and push the blue key to select diode function.
2. Connect black test lead to ” COM ” terminal and red probe to ” COM “,terminal and red probe to ” V- Ω ” input terminal.
3. Connect test probe and lead to the diode normally the forward voltage drop of good silicon diode is shown between. 400V to 900V If the diode under test is defective, ” 000 ” (short circuit) or ” OL ” (non conductance) is displayed.  Reverse check of diode if the diode under  test is defective ” 000″ or other value are  to be displayed.
