DISPLAY

RESULT OF “P” BUTTON

“Pro” < > “0” - Causes the indicator to return to normal display mode. Any changes to set-up data are permanently stored in the E2PROM.

“Pro” < > “1” - Entry into this module allows the user to select the Thermistor type, whether the display will read in degrees Fahrenheit (F) or Celsius (C), and display decimal point position.

“Pro” < >“2” - Entry into this module allows the user to select non-standard display slope and display offset values. This enables the meter to be “scaled” to a calibrated temperature probe. (This scaling is NOT required for most applications.)

“Pro” < > “3” - Module #3 allows the user to program what can be accessed from the front panel when the PGM. DIS. (Program Disable, TBA #3) pin is connected to common. This feature protects critical set-up data from accidental modification while allowing access to setpoints and other functions. The front panel lock-out menu (quick programming) includes setpoint modification, integrator/totalizer resetting, and peak/valley resetting.

Note: The term “Quick Programming” is used to refer to the ability to change the information that can be accessed from the front panel when the “PGM. DIS.” terminal is connected to “COMM.”.

“Pro” <> “4” - Module #4 programs the digital filtering level and the function of the remote input “E1-CON”pin (TBA #4), and if the totalizer option is installed, the remote input “E2-CON”pin (TBA #8). The functions of the remote E1 and E2 pins are the same and include display hold, peak/valley modes, totalizer reset, alarm reset, temperature offset, reading synchronization or print request.

“Pro” < > “5” - This module sets the time base, scale factor and low temperature disable function for the optional integrator/ totalizer.

“Pro” < > “6” - This module allows programming for the basic configuration of the alarm option. The programming includes HI/LO acting, tracking, alarm display, latched or auto-reset, assignment to either the input or the integrator/totalizer, and alarm and hysteresis values.

“Pro” < >“7” - Module #7 is the serial communication parameter programming. Baud rate, unit address, print request function and condensed prints are all programmable.

“Pro” < > “8” - This module allows digital scaling of the retransmitted analog output. Display values that correspond to 4 mA or 0 VDC and 20 mA or 10 VDC are keyed-in to scale the output and it may be assigned to either the input or the integrator / totalizer.

“Pro” < > “9” - This module is the service operation sequence and is not normally accessed by the user. This step re-calibrates the basic input and is used to compensate for long-term drift. Execution of this module should be done by technicians with the proper equipment in accordance with a maintenance plan of yearly recalibrations. A code number entry step is used to protect from inadvertent entries. Also, there is a number of other access codes which provide test and set-up changes as an aid in troubleshooting.
