gas. The software is flexible enough to allow you to configure the alarms so that you can have 2 alarm
levels for each gas.
CO Alarm 1 = 20 PPM
CO Alarm 2 = 100 PPM
CO

Alarm 1 = 20 PPM
CO

Alarm 2 = 100 PPM
In this example, CO Alarm 1 & CO
2
Alarm 1 will both be associated with the “Alarm 2” relay on the rear panel.
This allows you do have multiple alarm levels for individual gasses.
A more likely configuration for this would be to put one gas on the “Alarm 1” relay & the other gas on the “Alarm
2” relay.
CO Alarm 1 = 20 PPM
CO Alarm 2 = Disabled

Alarm 2 = 100 PPM
“Alarm 4” Relay
This relay is connected to the “range bit”. If the instrument is configured for “Auto Range” & the
instrument goes up into the high range, it will turn this relay on.
