CALIBRATE THE ANALOG OUTPUT
The analog output is factory calibrated. Recalibration is not
needed when the output type is changed.
If, for any reason, a new calibration has to be performed,
each output type could be easily calibrated.
To calibrate the voltage type analog output follow the steps:
• Connect a voltmeter to the pin 1 and 2 of the
output connector
• Enter in menu mode and select “General
Menu” - “Analog Output” sub-menu
•Select the analog output type to one voltage
output range 0-10mV, 0-100 mV or 0-1V.
• Select “Cal. Analog Out Max” and press “Up”
and “Down” keys until the read value is equal with the
maximum of the selected range (10mV, 100mV or 1V).
•Save the new coefficients by pressing “CFM” key.
•Select “Cal. Analog Out Min” and press “Up” and “Down”
keys until the read value is equal with 0V.
•Save the new coefficients by pressing “CFM” key.
To calibrate the current type analog outputs, follow the steps:
•Connect an ammeter to the pin 2 and 3 of the
output connector.
•Enter in menu mode and select “General
Menu” - “Analog Output” sub-menu
• Select the analog output type to one current
type 0-20mA or 4-20 mA.
• Select “Cal. Analog Out Max” and press “Up”
and “Down” keys until the read value is equal
with 20 mA.
• Save the new coefficients by pressing “CFM” key.
• Select “Cal. Analog Out Min” and press “Up” and “Down”
keys until the read value is equal with 0mA or 4 mA. The
analog output source current and when calibrating 0mA, a
positive value must be set for current (0.1mA for example)
and then the current must be slowly decreased to 0mA.
• Save the new coefficients by pressing “CFM” key.
