Important Note
PP Systems recommends Zero Time to be set to 40 minutes or less. Without frequent auto-zeroing, the
EGM-5 could potentially drift and lose calibration accuracy beyond the 1% specification.
For those customers who are in a very stable environment and where the auto-zero sequence
causes experimental problems, higher than 40 minutes can be used, but it should be used with
extreme caution.
Once the desired values are displayed in the Zero Settings screen, the “Back” button is selected to return
to the Settings 1 Menu.
Alarms Settings
This function allows the user to change/view the low (ALARM1) and high (ALARM2) alarm functions that
are built into the EGM-5. An alarm consists of an audio beep (if enabled in the Alarm Sound Setting

closure. There is a relay switch for each alarm: low (ALARM1) and high (ALARM2).
