4. MEASURING PROCEDURE
4-1 ACV measurement procedure
1)Rotate the function switch to the " ACV " position and
Power ON the meter.
2)Connect Red test lead to the " V Ω " input terminal and
Black test lead to " COM " input terminal.
3)Use the test lead measurement unknown AC voltage.
4)Read the Display. The show value will correspond to the position selected. If the Display shows " ---- ", it indicates an out-of-range measurement.
4-2 DCV measurement procedure
1)Rotate the function switch to the " DCV " position and
Power ON the meter.
2)Connect Red test lead to the " V Ω " input terminal and
Black test lead to " COM " input terminal .
3)Use the test lead measurement unknown DC voltage.
4)Read the display . The show value will correspond to the position selected. If the Display shows " ---- " it indicates an out-of-range measurement.
Remark :
* Observe polarity when measuring DC voltage.
4-3 Resistance measurement procedure
1)Rotate the function switch to the Ω position and Power
ON the meter.
2)Connect red test lead to the " V Ω " input terminal and black test lead to " COM " input terminal .
Connect test lead to the resistance.
7
3)Read the display . The show value will indicate correspond to the position selected. If the display shows " ---- " it indicates an out-of-range measurement.
4)When resistance < 4 Ω the buzzer will continuity beeper .
4-4 Watt measurement procedure
1)Rotate the function switch to the " WATT/Leakage " position.
2)Make sure your equipment work voltage, such as 110 V or 220 V.
3)Plug in the power source to " AC POWER INPUT " terminal, it locate the left position of Top Panel.
4)Plug in the equipment power line to the " LOAD " Terminal, it locate the right position of Top Panel.
5)Turn on the equipment power switch.
6)It can read the Power Consumption value on the top LCD
Display. At the same time. If your equipment exist current leakage. It will show the leakage current value on the bottom LCD Display.
4-5 V ( voltage ) A ( current ) measurement procedures
When your equipment is on working. You can rotate the function switch to V A Position. The upper value will show working voltage. The bottom value will show the current consumption value.
5. MAINTENANCE
1)The meter is intended for measuring the TRUE RMS
POWER VALUE, at the same time it also can measure the leakage current value to verify if the measurement equipment is under safety condition or not.
2)When measuring POWER VALUE, the working voltage of measurement equipment must be checked before turn on the equipment.
8
3)Instruments used in dusty environments should be stripped and cleaned periodically.
4)Do not leave the instrument exposed to direct heat from the sun for long periods.
5)Before removing the battery compartment cover, ensure that the instrument is disconnect from any circuit and the power switch is on the OFF position.
6. RS232 PC SERIAL INTERFACE
The instrument has RS232 PC serial interface via a 3.5
mm terminal ( 3-11, Fig. 1 ).
The data output is a 16 digit stream which can be utilized for user's specific application.
A RS232 lead with the following connection will be required to link the instrument with the PC serial port.
Meter PC
(9W 'D" Connector)
Center Pin..........................Pin 4
(3.5 mm jack plug)
Ground/shield.......................Pin 2
2.2 K resistor
Pin 5
The 16 digits data stream will be displayed in the following format :
D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0
9
Each digit indicates the following status :
D0 End Word
D1 & D8 Display reading, D1 = LSD, D8 = MSD
For example :
If the display reading is 1234, then D8 to
D1 is : 00001234
Decimal Point(DP), position from right to the D9
D10 left
0 = No DP, 1= 1 DP, 2 = 2 DP, 3 = 3 DP
Polarity
0 = Positive 1 = Negative

7. BATTERY REPLACEMENT
1)When the left corner of LCD display show " " , it is necessary to replace the battery, However in -spec.
measurement may still be made for several hours after
Low Battery Indicator appears before the instrument become inaccurate.
