3. LOW BATTERY Light
Amber LOW BATTERY light comes on when battery voltage falls to where the
instrument will not function properly (about 7. 0V). Batteries should be replaced
at this time.
4. NORMAL Light
The green NORMAL light acts as a pilot light and glows when the instrument is
turned on. At the same time the red ALARM light flickers faintly at intervals of
about one second.
5. REM ALARM
A miniature size phone jack is provided for plugging in a remote alarm device so that
the alarm sound can be repeated at a distance from the instrument. The outer shell
of the jack is grounded to the case, and is negative. This jack will be energized at
battery voltage (about 8.5 VDC when operating from “fresh” internal batteries; about
8.9 VDC when operating from continuous operating adaptor, P/N 80247 and about
12 VDC when operating from an external 12 volt battery )whenever instrument is in
alarm condition. The P/N 80444 Alarm Repeater is CSA Approved as a remote
alarm device.
.
WARNING:
THE INTRINSIC SAFETY OF THE INSTRUMENT IS VOIDED WHEN ANY
OTHER ACCESSORY IS USED AT THE REM. THE IMPEDANCE OF ANY
CONNECTED LOAD DEVICE AT THE REM MUST BE AT LEAST 22 OHMS (FOR 12
VDC OPERATION) OR AT LEAST 12 OHMS (WHEN OPERATING FROM INTERNAL
BATTERY OR CONTINUOUS OPERATING ADAPTER, P/N 80247) TO AVOID DAMAGE
TO THE INTERNAL CIRCUITS.
C. BOTTOM
A rectangular opening in the bottom allows clearance for the detector which is mounted
to the upper face of the bottom plate. The bottom plate is held in place by two knurled
thumbscrews. The sample inlet fitting and tubing extends from the outer face of the
bottom plate.
D. RIGHT SIDE
These items are aligned toward the rear of the right side panel.
1. Battery Compartments
There are two battery compartment drawers near the top. They contain the two
9V “transistor” type alkaline batteries, connected in parallel, which power the
instrument.
