RKI Instruments Beacon 200 - Manual (Page 47)

Calibration Program • 47
Entering the Calibration Program
1. Assemble the calibration kit(s). See the instruction manual for each
detector head for procedures specific to that detector head.
2. Simultaneously press and hold the ENTER and UP/YES buttons for
approximately 5 seconds to enter the Calibration Program. Release the
buttons when the CALIBRATION PROGRAM... message displays and
asks if you want to continue or return to normal operation.
NOTE: While in the Calibration Program, the alarm status of the Beacon
200 will be locked in the state it was when the Calibration Program
was entered.
3. Press the ENTER button to continue and display the Calibration Time-
out setting.
The Beacon 200 will remain in the Calibration Program for the amount
of time indicated by the Calibration Time-out setting or until you exit the
program. If necessary, adjust the setting using the UP/YES and DOWN/
NO buttons. Make sure you have allotted enough time to perform the
calibration procedure. Consider the type of detector head(s) installed
and the distance from the Beacon 200 when determining the time
required.
NOTE: If you do not accept a Time-out setting and stay at this screen or
press ESCAPE and do not press control buttons again, then the
Beacon 200 will exit the Calibration Program and begin its warm-
up period 5 minutes after the last button was pushed. This warm-
up period functions as if the unit were just powered up.
4. Press the ENTER button to accept the Time-out setting, start the Time-
out period and continue in the Calibration Program.
NOTE: The following describes calibration with a typical channel
allocation which may be different from yours. This example
allocation has two active channels with both types of detector
heads installed. Channel 1 is a 4-20 mA detector head and
channel 2 is a direct connect detector head. See the detector
head instruction manuals for calibration information and
procedures specific to the detector heads.
