" ( 3-12, Fig. 1 ). The meter will permanent power ON
when use the DC ADAPTER power supply ( The power
Button function is disable ).
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.
2) Loose the screws of the " Battery Cover " ( 3-13, Fig. 1 )
and take away the " Battery Cover " from the instrument
and remove the battery.
3) Replace with DC 1.5 V battery ( UM3, AA,
Alkaline/heavy duty ) x 6 PCs, and reinstate the cover.
4) Make sure the battery cover is secured after changing
the battery.

If the meter happen the troubles such as :
CPU system is hold ( for example, the key button can
not be operated... ).
Then make the system RESET will fix the problem.
The system RESET procedures will be either following
method :
During the power on, use a pin to press the " Reset
Button " ( 3-11, Fig. 1 ) once a while will reset the
circuit system.
The instrument has RS232 PC serial interface via a 3.5
mm terminal ( 3-10, 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)
Pin 4
(3.5 mm jack plug)
Pin 2
Pin 5

2.2 K
resistor
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
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
D9 Decimal Point(DP), position from right to the
left
0 = No DP, 1= 1 DP, 2 = 2 DP, 3 = 3 DP
D10 Polarity
0 = Positive 1 = Negative
D11 & D12 Annunciator for Display
℃ = 01 ℉ = 02
D13 When send the upper display data = 1
When send the lower display data = 2
D14 4
D15 Start Word
