11. The adjustment mode now shows the value of the selected parameter from both
instruments, and a delta parameter (for example,
ΔRH
) that shows the difference
between the two.
Wait at least 15 minutes for the measurement to stabilize, and for the value of the delta
parameter to stop changing. Stabilization may take a much longer time, depending on
factors such as temperature differences and airflow around the sensors.
12. The difference between the reading should be no greater than the combined
measurement uncertainty of the HMDW110 series transmitter and the reference probe.
Depending on the result, proceed as follows:
• If the HMDW110 series transmitter is within its accuracy specification, there is no need
to proceed with the adjustment. Select
Back > Exit
to leave the adjustment mode.
• If adjustment is required, continue with the next step.
13. Select
Adjust > To same as RH (I)
14. The MI70 will ask
Do you really want to adjust?
. Select
Yes
.
MI70 shows the text
Adjustment done
and returns to the adjustment mode after a few
seconds.
15. Check the value of the delta parameter to verify that the adjustment has taken effect.
16. Select
Back
to return to the parameter selection screen.
17. Select a new parameter for adjustment and proceed as instructed above, or select
Exit
to
leave the adjustment mode.
18. Turn off the MI70 indicator and disconnect the connection cable from the service port.
19. Reconnect the terminal blocks and close the cover.
