4. MEASURING PROCEDURE
4-1 Power ON/OFF
1) Press the " POWER button " ( 3-2, Fig. 1 ) more than 1.5
seconds to Turn ON the meter.
2) Press the " POWER button " ( 3-2, Fig. 1 ) more than 1.5
seconds to Turn OFF the meter.
4-2 DCV measurement procedure
1) Press the " POWER button " ( 3-2, Fig.1 ) more than 1.5
seconds to Turn ON the meter.
2) Connect Red test lead to the " V " input terminal and
Black test lead to " COM " input terminal .
3) Then use the test lead measurement unknown DC voltage.
4) Read the value from top display. The value indicated
corresponds to the position selected. If the LCD show
" ---- ", it indicates an Out-of-range measurement.
5) If the LCD show in " dcv Error " , and the beeper is
continuously turn on, please change voltage polarity .
4-3 DCA measurement procedure
1) Press the " POWER button " ( 3-2 , Fig.1) more than 1.5 seconds
to Turn ON the meter.
2) Connect red test lead to the " COM " input terminal and
black test lead to " 10A " input terminal .
3)
Then use the test lead measurement unknown DC current.
4) Read the value from bottom display . The value
indicated corresponds to the position selected. If the
display shows " ---- " it indicates an Out-of-range
measurement.
4-4 DC WATT measurement procedure
1) Press the " POWER button " ( 3-2 , Fig.1) more than 1.5
seconds to Turn ON the meter.
2) Turn OFF the DC POWER SOURCE.
5

3)
Plug in the DC POWER SOURCE to " WATT " terminal
and " 10A " terminal ( 3-7 , Fig.1).
Turn ON the DC POWER SOURCE.
4) Read the value from top display. The value indicated
what voltage to test.
Then turn OFF the DC POWER SOURCE.
5) Make sure your unknown elements or equipment
working voltage and voltage polarity .
6) Press the " FUNCTION button " ( 3-3 , Fig.1) once then
change function for measuring DC WATT.

side of LCD will show in " DATALOGGER " .
3) On the bottom side will show in " 2.000 A ", means
maximum work current are 2 A, you can press " HOLD
button " ( 3-4, Fig. 1 ) once to change for maximum
current 10 A, and LCD will show in " 10.00 A " .
4) Now you can turn on the equipment power switch or
turn on the DC POWER SOURCE .
6

5) Then press " REC button " ( 3-5, Fig. 1 ) to execute data
logger function, and LCD will show in " REC " at the top
of display.
6)
When finish data logger function " REC " symbol will
disappear, " SET " symbol will show on LCD left side.
7)
If you press " FUNCTION button " ( 3-3, Fig. 1 ) , meter will
send data from " RS-232 output terminal" ( 3-8, Fig. 1 ).
through RS232 cable ( UPCB - 02 ) or USB cable ( USB -
01) into the computer and recording to the software
SW-E2005 ( optional ) or DL-2005 ( optional ).
8)
When finish data transmit , " EMPTY " symbol will show
show on LCD on left side automatically.
9) If you intend to exit Data logger function. press the
" FUNCTION button " ( 3-3 , Fig.1) and " HOLD button " (
3-4 , Fig.1) at the same time again more than 3 seconds ,
will leave Fast data logger mode.
10) The record numbers of Data logger is 300 records. The
duration time of Data logger is 5 seconds.
4-6 Data Hold
During the measurement, press the " Hold Button " ( 3-4,
Fig. 1 ) once will hold the measured value & the LCD will
display a " HOLD " symbol.
Press the " Hold Button " ( 3-4, Fig. 1 ) once again will release
the data hold function.
4-7 Data Record ( Max., Min. reading )
1) The data record function records the maximum and
minimum readings. Press the " REC button " ( 3-5, Fig.
1 ) once to start the Data Record function and there
will be a " REC. " symbol on the display.
