Current Detection Reading
This reading displays the current PPM STP level of the selected refrigerant.
Log Interval
The HGM-MZ retains a data log of 100 measurements for each zone. The log interval is the number of
minutes from 1 to 1440 between each log point. This parameter can be changed from Zone Setup Screen #1
(page 32).
The default setting for this parameter is 1440 minutes (24 hours). If the log interval time is set to 0, then a
measurement is recorded in the trend log after every measurement cycle. Therefore, after the trend log is
filled, it will contain the last 100 measurement points for a zone. If you want the data logged less frequently,
increase this value. It is important to remember that cycle time is dependent on many factors, including the
number of zones monitored, input line length, and the run zeroing mode selected. Before changing this value
it may be useful to first review the log data using the Trend Screen to determine the nominal cycle time.
