permanently stored in the unit’s configuration memory. The IFMA automatically
selects the proper calibration setting for the selected Operation mode.
changed using the calibration routines. The Minimum output value can be
adjusted to any value less than the Full Scale output value, and the Full Scale
value can be adjusted to any value greater than the Minimum value.
Specified accuracy for modes 2, 3, and 4 holds until the factory calibration
range has been halved. This does not apply to mode 1, since it already uses only
half of the IFMA’s output range. When increasing the output range, the new
calibration settings can not exceed the factory Full Scale value by more than
10%. The 0 to 5 VDC range can be doubled.
calibration is changed for one operating mode, and the user then selects a
different operating mode, the unit reverts to factory calibration settings.
Calibration steps can be combined (added) to obtain a total calibration change.
This is done by repeated push-button entries of the same value, or different
values, before saving the change. The calibration steps as shown in the table at
right are approximations. A current or volt meter should be connected to the
appropriate output pins to verify the actual calibration setting.
5.0 Maximum Response Time Setting (Low Frequency Cut-Out Setting)
6.0 Calibration
The IFMA is factory calibrated for all operating modes. These settings are
The Minimum and Full Scale output values established at the factory can be
Changing the factory calibration settings does affect the accuracy of the unit.
The IFMA can store user calibration settings for only one mode at a time. If
