The iQ series instruments provide for the ability to calibrate the analog
outputs (both voltage and current) of the instruments. The basic procedure
for both voltage and current are the same using the following procedure:
●
Complete the connections of the recording device to the desired analog
output channel. (See page
8-5 for the channel information).
●
Calibrate the output channel low level.
Note When calibrating the current output when using the 0-20 mA
scale, the low level will be set to 4 mA due to the inability to adjust the
actual current output to below zero.
▲
●
Calibrate the output channel full scale.
