MODEL 1054B C
4.4 TEMPERATURE. Display Mnemonic t-C. Select this item
for temperature reading and compensation choices.
A. Temperature Display. Display Mnemonic d-t. Select
this item to toggle between °F and °C temperature dis-
play. The analyzer will show all temperatures in units
selected until the selection is changed.
B. Automatic Temperature Compensation. Display
Mnemonic Atc. The analyzer will use the temperature
input from the sensor for temperature correction when on
is selected. When oFF is selected, the analyzer will use the
value entered by the user for temperature correction. This
manual temperature option is useful if the temperature
sensor is faulty or not on line. Temperature specific faults
will be disabled (refer to Section 8.0).
4.4.1 Temperature Configuration t-C. Refer to Figure 4-4.

4.5 CURRENT OUTPUT. Display Mnemonic is OUt. This
item is used to configure the output signal.
A. Output Dampening. Display Mnemonic dPn.
Dampens the response of the signal output. This option
is useful to minimize the effect of a noisy reading. The
number entered is the sample time (in seconds) for an
averaged output. Zero to 255 seconds may be entered.
B. mA Output Range. Display Mnemonic CUr. Selection
of this item will allow choice of 0 to 20 mA or 4 to 20 mA
output range.
C. Display Output. Display Mnemonic d-O. This item is
used to select logic of output display. Selecting this item
will allow the analyzer to display current output as mA
(doc) or as a percent of full scale output range (Pct).
