8.5 Calibration procedure
8.5.1 General notes
If the antenna is not in the same customer order as the signal converter, it is necessary to
calibrate the device.
Equipment needed
• A device with the integrated display option.
• Process measurement and device configuration software (e.g. the DTM for PACTware™), if
the device does not have the integrated display option.
• An ammeter.
• Reference device: an approved level meter or indicator
Requirements
• The ammeter must be correctly calibrated and connected directly to device.
• You must have 2 reference points (levels) in the tank given by a different measurement
solution. These points are identified as "ref_pt1" and ref_pt2".
CAUTION!
Do not connect the ammeter across the safety system PLC because this configuration can open
the circuit breaker.
Make sure that the 2 reference points are not in the top or bottom dead zones.
