4.2.3. Distance + EXH
This parameter defines the combined length of the sample tubing plus any tubing on the exhaust port. Total
length should not exceed 1200 ft.
1. Press the ENTER key to adjust the setting.
2. Use the LEFT/RIGHT cursor keys to move across the entry field and the UP/DOWN cursor keys to
modify the individual characters.
3. Press ENTER to accept the new entry or ESC to revert to the previous setting.
4.2.4. Temp @ Zone
This parameter is used to set the expected temperature of the air at the zone being sampled. The value is
used to calculate the STP PPM value shown in the diagnostic screen only.
1. Press the ENTER key to adjust the setting.
2. Use the LEFT/RIGHT cursor keys to move across the entry field and the UP/DOWN cursor keys to
modify the individual characters.
3. Press ENTER to accept the new entry or ESC to revert to the previous setting.
4.2.5. Current Detection Reading
This reading displays the current PPM level of the selected gas.
4.2.6. Log Interval
The 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.
The default setting for this parameter is 10 minutes. 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.
4.3. Navigating to the 2
nd
Zone Setup Screen
Select the MORE option at the bottom right side of the first Zone Setup screen to continue to the next
screen containing more options. This screen displays the peak PPM value in the upper left side of the
screen.
