2. After the connections stabilize (about 10 seconds), request the gain
calibration by setting bit 01 in BTW word 28 and sending a block transfer
write (BTW) to the module. Refer to Table 7.A.
When the BTW is sent, all channels are calibrated to +100.00mV.
NOTE: Normally, all channels are calibrated simultaneously (bits 08–15
of word 28 are octal 0). To disable calibration on any channel, set the
corresponding bit 08 through 15 of BTW word 28.
3. Queue BTRs to monitor for gain calibration complete and any channels
which may not have calibrated successfully.
