15.2 INPUT ADJUST
Notes
1. Input adjust cannot be applied to input channels with input type of ‘Digital’, ‘Test’ or ‘comms’.
2. Input adjustments can be carried out only by users with ‘Adjust I/O’ permission (
see section 4.4.1
).
3. The instrument must be powered for a suffi cient time (e.g. 30 mins) for it to reach thermal equi-
librium before an input adjust is performed.
4. The highest numbered channel on each input board (i.e. input channels 6, 12, 18 etc.) are refer-
ence channels and cannot be adjusted
This facility allows the user to compensate for tolerance errors etc. The technique used is to select those
channels to which adjust is to be applied, then for each channel to:
a
apply a known low level signal (at or close to the low input range value) to the relevant input. When
the recorder reading is steady, press ‘Apply’.
b. apply a known high level signal (at, or close to, the high input range value) to the relevant input.
When the recorder reading is steady, press ‘Apply’.
Figure 15.2a shows the initial display. Channels 1 to 6 are selected by default.
