Calibration Connector for the HMI41

The following numbers refer to Figure 4 above:

1 = For calibration with the HMI41, insert the jumper as indicated

here.

2 = Calibration connector for the HMI41

NOTE

The serial communication parameters are:

1200 bauds, no parity, 8 data bits, 1 stop bit

NOTE

When the connection is being established, the message 'CON ERROR'
blinks on the HMI41 display for a couple of times after which
measurement readings appear. This is quite normal and requires no
action; however, if the message is not replaced by measurement readings,
it is an indication of an operation error.

NOTE

Do not interrupt the calibration procedure. In case of an interruption or a
power failure, the normal mode is restored by completing the calibration
or resetting the module. Reset the module by switching off the supply
power of temperature channel.
