Gain Calibration
Calibrating gain requires that you apply 402.00 ohms across each
input channel.
Normally all inputs are calibrated together. To calibrate the gain of
an input, proceed as follows:
1. Connect 402.00 ohm resistors across each input channel as shown
in Figure 6.2 below.

2. Apply power to the module.
3. After the connections stabilize, request the gain calibration by
setting bit 01 in BTW word 15 and sending a block transfer write
(BTW) to the module.
NOTE: Normally, all channels are calibrated simultaneously (bits
10–15 of word 15 are octal 0). To disable calibration on any channel,
set (1) the corresponding bit 10 through 15 of word 15.
