4.2.8 Selecting the Method and Value for Ambient
Temperature (tAnb)
• Turn the rotary switch to the SET-UP position.
• Press the
▲ button
until “tAnb” appears on the top line of the dis-
play.
• Press the ► button to enter the ambient temperature sub-menu.
• The rst choice here is to decide if ambient temperature will be
measured using the RTD temperature probe accessory or if it will
be programmed using the same method as described for refer-
ence temperature. “Prb” (measure the ambient temperature using
the RTD probe accessory) or “nPrb” (no probe, manually enter
the ambient temperature) will be displayed, press the
▲ button
to
toggle between the two choices.
• If measuring the ambient temperature is desired, press the ►
button when “Prb” is in the display. The lower display will momen-
tarily show dashes “-----” and then return to the top level ambient
temperature menu.
• If manually entering the ambient temperature is desired, press the
► button when “nPrb” is in the display. The ambient temperature
may now be manually entered.
• The current programmed ambient temperature will be displayed
with the leading digit ashing.
• Use the
▲ button
to change the leading digit. The minus (-) symbol
can also be programmed in this location.
• When the desired value is reached, press the ► button to move
the next digit to the right.
• Use the
▲ button
to change this digit then press the ► button to
again move to the next digit to the right.
• Repeat this process for each of the 5 digit locations.
• After the 5th digit is programmed, press the ► button again to
return to the top level of the ambient temperature set-up menu.
•
To proceed to the next programming variable, press the ▲ button.
NOTE: The program limits for the reference temperature are 32.0 to
130.0°F and -10.0 to 130.0°C. Attempting to set values outside these
limits will cause error message “Err23” (Entry Out of Range) to appear in
the display.
