Chapter 4 Calibration
The ICA3 and ICA6 S and H versions can be calibrated with the transducer connected provided that two calibration
points can be implemented e.g. by applying known weights or forces. If this is not possible, a stable mV source or
load cell simulator can be used if the precise sensitivity (mV/V) of the transducer is known.
Figure 4.1 Connection Details for Calibration
See figure 2.3 for ICA6 power connections.
1.
Apply the known
low calibration conditions (weight, force or mV/V). This may be zero if required, and set
the output to approximately 0.1V using the ‘Z’ potentiometer. Note the exact reading.
2.
Apply the known
high calibration conditions (ideally between 75% and full scale) and adjust the ‘S’
potentiometer to give the required
change in output voltage for the known input (e.g. 10V change for the
±10V calibration).
3.
Apply the known
low calibration conditions and re-adjust the Zero if required.
Chapter 5 The ILE Enclosure
The ICA3 and ICA6 can be mounted in Mantracourt’s ILE enclosure which provides environmental protection to IP67,
full electrical screening and PG7 cable glands.
When using the ILE enclosure with an ICA6, the output connection should be dressed into one of the semi-circular
cut-outs in the lower PCB the as shown below in order to avoid the output cable being trapped when the cover is
slid in place:
