7. POWER SUPPLY from DC ADAPTER
The meter also can supply the power supply from the
DC 9V Power Adapter ( optional ). Insert the plug of
Power Adapter into " DC 9V Power Adapter Input Socket
" ( 3-11, Fig. 1 ). The meter will auto select to DC 9V Power Adapter .
8. 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.
2) Loose the screws of the " Battery Cover Screws " ( 3-12,
Fig. 1 ) and take away the " Battery Cover " ( 3-15, Fig. 1 )
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.
9. SYSTEM RESET
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 " ( 3-10, Fig. 1 ) once a while will reset the
