3.5 Calibration Amplifier Gain Check
Use this procedure to display the gain values of the calibration amplifier circuits in
hexadecimal. This procedure is useful to service technicians for troubleshooting
purposes.
1.
From the Main Screen select
Menu
>
Calibration
>
Calibration Gains
to display the
Calibration Gains Screen.
Where: #### is the gain value in hexadecimal. Hexadecimal (or “hex”) is like
decimal, except:
•
hex uses the 16 hex digits 0-9 and A-F (vs. using only the 10 digits 0-9 in
decimal notation), and
•
each position in a hex number is an exponent of 16 (16
0
=1’s place,
16
1
=16’s place, 16
2
=256’s place, etc.) rather than an exponent of 10 as in
decimal (i.e., 10
0
=1’s place, 10
1
=10’s place, 10
2
=100’s place, etc.).
For example, a gain value of 298 decimal (or base 10) equals 012A hex (or base
16).
2.
Press
ESC
three
times to return to the Main Screen.
3.6 Erase Calibration Procedure
The following procedure resets the gain of each calibration amplifier circuit to the
factory default hexadecimal value of “FFFF”.
1.
From the Main Screen select
Menu
>
Calibration
>
Erase Calibration
to display the
Erase Calibration Screen.
2.
Select
Yes
to erase the calibration values. Observe that the message “Erasing
Calibration” appears at the bottom of the screen. Select
No
to abort this procedure
and return to the Calibration Menu Screen.
3.
Press
ESC
twice
to return to the Main Screen.
