Settings for circuits B to D (when measuring 2 circuits or more)
This product can measure up to 4 circuits. If you increase the number of circuits, you must enable the circuits and set
the items for them. (
17) Make sure you disable those circuits you are not using.
You cannot set the communications addresses for circuits B to D individually. It is set automatically as follows based
on the setup values of circuit A.
Caution
• A communication address greater than 99 is invalid.
1
Enable just those circuits from B to D that will be used (Ex.: enable circuit C)
If a measured value is displayed, press and hold the [MODE• ] key and enter your password to switch to the setting mode.
