Model 610 7

This unit comes complete with three (3) nickel cadium batteries and 9VAC power adapter for

battery charging, eliminating the need to ever buy, or replace batteries. Under normal operating

conditions, the batteries require charging once a month.

• The battery operated alarm is activated by turning the battery switch “On”.

• If the sensor probe is immersed in Liquid Nitrogen, there is no audible signal from the alarm unit.

When the sensor is removed from the liquid nitrogen, the audible signal will sound

in a few seconds (5 to 15 typically.)

• The audible signal can be tested when the sensor is immersed in liquid nitrogen by pushing the

“Push toTest” button. The audible signal will sound for 5 days contiuously depending on the

charge level of the batteries.

• The audible signal can be silenced by correcting the low liquid nitrogen level problem, or turning

the battery switch to “Off”.

• In the event that the single thermistor should open or break, a tone will alert the operators.

• The battery and alarm horn can be tested at any time.

• When the batteries begin to go low, the unit produces an audible sound.
