j) You will hear “Enter number then press pound”
k) Enter the value then press #.
► Use * to program a negative number (i.e. *20 = -20º)
► Acceptable range is -999 to 999
l) You will hear the value you just entered (i.e. 50º)
m) Proceed to step 4.a
4. Programming the callout delay time
a) You will hear "Callout time delay is x minutes press 1 to change” (default 0
minutes)
b) Press 1 to make a change
► Press 2 to skip and return to step 1.b
c) You will hear “Enter number then press pound”
d) Enter the time delay in minutes (i.e. 15 for 15 minutes or 0 minutes for an
immediate callout)
► Acceptable range is 0 to 900 minutes
e) You will hear the value you just entered
f)
Proceed to step 1.b
Repeat the steps 1 to 4 for each additional sensor.
Programming Temperature Corrections
The Four Zone Temperature Monitor allows the user to correct for small tem-
perature measurement errors due to sensor cable extension length for each
sensor. A calibrated standard must be used to obtain the actual temperature.
a) From the Main Menu, press 2 to Set Limits
b) You will hear “Enter Sensor Number"
c) Enter #
d) You will hear "Enter Sensor Number to Adjust"
e) Enter the number of the sensor you want to correct (1-8)
►To return to the Set Limits Menu press 0
f) You will hear "Enter Sensor Number x Actual Temperature, then press
pound"
g) Enter the actual temperature measured using the standard, then press #.
► The maximum the temperature measurement can be corrected is +-25º
from the currently displayed temperature.
(i.e. If the temperature currently being displayed is 100º, the max correc-
tion is 125º and the min correction is 75º. An “invalid" message is played
for larger corrections.)
h) You will hear the corrected temperature and the corrected temperature will
be displayed on the display.
