3-82 Model 5028i Instruction Manual
The Analog Output Calibrate Zero screen allows the user to calibrate
the zero state of the selected analog output. The operator must connect
a volt meter to the output and adjust the output until it reads 0.0 V
on the meter for a voltage channel, or either 0 or 4 mA for a current
channel (depending on the selected range). See the "set output to:" field
on the display.
In the Main Menu, choose Service > Analog Out Cal > select
l
Channel > Calibrate Zero.
The Analog Output Calibrate Full-Scale screen allows the user to
Scale
calibrate the full-scale state of the selected analog output. The operator
must connect a volt meter to the output and adjust the output until the
meter reads the value shown in the "set output to:" field, in either V or
mA, depending on the selected output channel.
In the Main Menu, choose Service > Analog Out Cal > select
l
Channel > Calibrate Full Scale.
The Analog Input Calibration menu is used to calibrate the 8 analog
input channels at both zero and full-scale. The analog input calibration
menu is visible only when the I/O expansion board is installed and
when the instrument is in service mode. For more information on the
service mode, see
Note This adjustment should only be performed by an instrument
service technician.
In the Main Menu, choose Service > Analog Input Calibration.
