Sampler Calibration

Instruction 0055-9017 43

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

=1’s place,

=16’s place, 16

=256’s place, etc.) rather than an exponent of 10 as in

decimal (i.e., 10

=1’s place, 10

=10’s place, 10

=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.
