Digital voltmeter
Fig. 6-3-5.
Adjusting method:
1) Adjust the regulated power supply output voltage so that the digital
voltmeter display becomes 6.1
±
0.1 Vdc.
2) Set data: 01 to page: 1, address: 00.
3) Set the camera recording mode.
4) Decrease the voltage so that the digital voltmeter display becomes
5.30
±
0.01 Vdc.
5) Select page: 2, address: 0E, and read the data displayed on the
adjusting remote commander, and take this value as D
30
.
6) Set D
30
to page: D, address: 30, and press the PAUSE button of
the adjusting remote commander.
7) Convert D
30
to a decimal digit, and take this value as D
30
´.
(Refer to the Hexadecimal-Decimal Conversion Table in “Data
Processing” in “Service Mode”.)
8) Calculate the adjustment data (decimal) from the following
equations (decimal calculation), convert the data to hexadecimal
digits, and input to each adjustment addresses.

Note:
After setting the data, be sure to press the PAUSE button
of the adjusting remote commander.
9) Set data: 00 to page: 1, address: 00.
10) Turn off the power supply.
5. Battery End Adjustment
Regulates the battery end voltage.
If the voltage changes, the life of the battery will be shorten, or the
battery end image will be distorted.
