Note
• After writing a set value, execute reset (manual or remote). It takes about 5 seconds for
restoration after resetting.
• The UPM100 can set the value of CT ratio down to the second decimal digit. However, when the
value is read out by the UPM01 communication protocol, decimal digits are truncated.
• The UPM100 is set to measure pulse width in increments of 10 msec. The UPM01
communication protocol truncates 1-msec-digit values.
• When a value out of the set value range is entered, a set value error is set to the status of the
response, and the currently set value is set to the response and returned.
