SmartDGA

®

Instrument

The indicator light on the front of the SmartDGA instrument is on for 5 seconds and off for

15 seconds, then repeats the cycle. This means that during a one minute period you have three
indication cycles on the SmartDGA instrument. The LED indication light on the EZHub will be the
same as on the instrument, except it will not flash and will be a solid indication. The color
indications are noted below:

Note:

A caution, warning, or alarm state can be caused by ppm level, rate of change, or

ratio limit being exceeded.
