If there was a momentary power outage (Brown out), the unit may not have had enough
time to recognize this and switch to battery mode. (The Chart Recorder may lock up or

that shares the circuit with other machinery that has phase motors or compressors that
cycle periodically. As these other machines cycle, they momentarily have a high current
draw, therefore drawing from the unit.
