Output calibration
Analog outputs can be calibrated by the Stations themselves.
Output 1 can be calibrated by input 1 and output 2 can be calibrated by
input 2.
The configuration of input hardware should be the same as for the output
(0 to 5V, 0 to 10V or 0 to 20mA) since the Stations themselves will be measuring the
output signal. Therefore, check that the configuration of the internal jumpers in the
Output Module Board and the CPU Board match the corresponding input and output
types.
Make sure the input type to be used for the output calibration has already been
properly calibrated.
Make the connections listed in table 7 according to the output module and output
signal should be calibrated.
Output type
current (0 to 20mA)
voltage (0 to 10V)
voltage(0 to 5V)
Table 7 - I/O terminal connections for output calibration
Now enter level 4 and select which of the two outputs will be calibrated. Select the
output signal (0 to 20mA, 0 to 5V or 0 to 10V) and press ENTER.
The display will show the mnemonic corresponding to the first calibration point.
There are two points of calibration.
In case of current output the mnemonics correspond to electrical signals from
0 to 20mA. In case of voltage the mnemonics correspond to signals from 0 to 5V or from
0 to 10V.
By pressing ENTER when the mnemonic corresponding to the first or second
calibration point is displayed, the display will show the output value. It will then be
possible to have the output value adjusted to the electrical level indicated by the
mnemonics with the help of the UP and DOWN keys. Press ENTER after adjusting.
When calibrating the first point (0mA, 0V) care should be taken to avoid output signal
saturation.
Return to normal operating level by moving back until level zero.
