The absolute input-output calibration of the gain ranges can be done that way that for a given input voltage 30 000 digits at the output are produced:

Table 7.2.2

The TC-value of the output (total measurement path) for G24 can be trimmed to a minimum value by selecting the best setting of the TRIMBTC

subregister of the TRR register (see 7.5.7).

A factory calibration is done for the amplifier offset (TRIMA).

This data is stored in the ZZR register. ZZR-register mapping is given in 8.6.2
