６-2-3 Confirmation of Battery Voltage Detection
･･････････････････････････････････････････････････････
This adjustment is required to absorb the individual difference of the battery voltage detection circuit.
For confirmation, perform it after replacing the batteries, too.
CAUTION
Make sure to perform this adjustment after replacing the MUX POWER , MUX CHARGE-04A
or XCONT PCB, too
.
Ⅰ
Setting of battery voltage detection adjustment mode
Set to ON the DIP switch SW3-8 on the NEXSC PCB, and turn on the power.
Press the leg scan key in the APR to enter the + side battery voltage adjustment mode. Press the foot scan key
in the APR to enter the - side battery voltage adjustment mode. In each mode, the converted detected voltage is
displayed in 6 digits in the tube voltage and current time product display units.
(The LED on the leg or foot scan key flickers.)
Ⅱ
Adjustment of battery voltage
Measure the battery voltage, make the error between the measured value and the displayed value to ±0.2V or less
using the tube current time product setting keys “+” or “-” key. Then, press the program registration key.
Battery voltage on the + side : Measured between TER3 and TER5 on the MUX POWER PCB
Battery voltage on the – side : Measured between TER5 and TER4 on the MUX POWER PCB
