7.9.6. Programming New Gases
As new gases come into use, the RLDS allows the
addition of these new gases to its on-board gas library.
At the end of the gas library list is an option labeled
CUSTOM
for adding new gases. From the
Calibration screen
use the left/right arrows to select
CUSTOM
from the list of refrigerants. Next, press
ENTER
, and use the up/down arrow keys to enter the
calibration factor.
The selection of the matching gas and
CAL
factor is
performed by analyzing the new refrigerant. Once the
matching gas is determined, field calibration is
possible by using the same procedure as for other
refrigerants. When the new gas entry is complete,
simply set up the appropriate zone for
CUSTOM
.
Program the instrument for a new gas as follows:
1. From the
Calibration screen
, use the
PREV
GAS
or
NEXT GAS
options to scroll through
the list of available choices until the
CUSTOM
option is displayed.
2. Select the
CUSTOM
option. Press
ENTER
to
accept the new entry or
ESC
to revert to the
previous setting.
3. Enter the new CAL Factor as received from
Emerson.
7.10.Zone Hold Mode
A zone can be placed on hold and continuously
monitored for a length of time determined by the
Zone Hold Time
value. To place a zone on hold,
select the zone at the main run screen, then press and
hold down the
ENTER
key until the unit beeps. The
word “
HOLDING
” will appear in the status box.
While in the hold mode, further investigation of the
zone’s status can be made by navigating to that
Zone’s
Setup Screen #1
. To release the zone from the hold
mode, press and hold down the
ENTER
key until the
unit beeps and the screen display returns to normal.

IMPORTANT: Do not alter any other
parameters within the Calibration Menu as
this will alter the factory calibration.
