Operation

3.1 Set Up

The only set-up required for the Primalarm is the attachment of one end of the power cord (converter) to the unit and the other end into a properly grounded AC outlet as noted in Section 2.

When power is first applied to the unit, the alarm and one or more of the LED's may light. After a maximum of three seconds, the indicators will extinguish and the alarm will reset.

The unit should now be operational with the OPERATION INDICATOR LED flashing on or off with each background pulse received.

The Primalert 35 is a fully digital preset count instrument. The measurement and reset time are dependent on count rate. Refer to the response time specifications listed in Section 2.

3.2 Testing

Test the unit for proper operation by positioning the check source (P/N 62-103) as indicated on the front panel. With the check source label down, the Primalert 35 should indicate between 2 and 8 mR/h; with the label up, it should indicate between 1 and 4 mR/h.

3.3 Setting the Alarm Level

The Alarm Level may be set with a small screwdriver from the front panel. Alarm levels from 1 to 32 mR/h may be set. When the radiation exceeds the setting, the alarm will be actuated.

3.4 Alarm Reset

The alarm reset on the Primalert 35 is automatic and both aural and visual alarms will stop when the radiation level drops below the Alarm Level setting.
