time constant, the slower the system reacts to changes of the mea-
sured value.

tion. During cal. and hold time the signal outputs are frozen, alarms
and limits are not active.

The instrument is equipped with an internal logger. The logger data

Date, time, alarms, measured value, flow, raw value, signal, refer-
ence, case temperature.
4.3.1 Log Interval: Select a convenient log interval. Consult the table be-
low to estimate the max logging time. When the login buffer is full,
the oldest data record is erased to make room for the newest one.
(circular buffer)

data series is started.
