(2) History of maximum and minimum
measurement values
The maximum and minimum measurement values
of Sensor1, Sensor2 (for the 2-input model only),
and terminal block, obtained after factory shipment
(or after these values are cleared) for each
measurement value of terminal block temperature
(TERM) have been recorded in the temperature
transmitter.
The maximum and minimum values can be
checked by referring to the following parameters.

NOTE
The above variables may become large due to
sensor disconnection or others. If it occurs, clear
them by following the procedure below.
Also, you can clear the maximum and minimum
values of Sensor1 and Sensor2 (for the 2-input
model only). If cleared, the subsequent maximum
and minimum values start to be updated
immediately. Use the following parameters to clear
these values.

Option
Remarks
P05:LOG
CLEAR
NO RESET
The values are not
cleared. This is usually
used. System returns to
this state after clearing of
values.
RST
SENSOR1
Only Sensor1 is cleared.
RST
SENSOR2
Only Sensor2 is cleared.
(It is displayed for the
2-input model only.)
RST S1&S2
Sensor1 and Sensor2
are cleared. (It is
displayed for the 2-input
model only.)
(3) Operating time
The operating time of the transmitter after factory
shipment is shown. It can be checked using the
following parameters.
Parameter
Remarks
P30:OPERATE
TIME
The operating time is displayed in
“DDDDDdHH:MM” format. “DDDDD”
is the number of days. The number of
digits may increase or decrease within
the range of 1 to 5 days according to
the actual number of days. “HH” is
hours, and “MM” is minutes.
NOTE
The operating time is saved in the non-volatile
memory every 15 minutes.
