PROGRAMMING METHODS
Four front panel push buttons, PC and MeterView software, or cloning with Copy feature.

NOISE FILTER
This function averages any minor or quick changes in the input signal and displays the reading with greater stability. Increasing the filter value will help stabilize the display. Programmable between 2 and 199 (to disable filter program 0).

DISPLAY UPDATE RATE
Process/RTD: 3.7-5/sec; T/C: 1.8-2.5/sec

OVERRANGE
Display flashes 9999

UNDERRANGE
Display flashes -1999

RECALIBRATION
All ranges are calibrated at the factory. Recalibration is recommended at least every 12 months.

MAX/MIN DISPLAY
The maximum and minimum readings reached by the process are stored until reset by the user or until power to the meter is turned off.

PASSWORD
User programmable

NON-VOLATILE MEMORY
All programmed settings are stored in non-volatile memory for a minimum of ten years if power is lost.

DATA ACQUISITION
MeterView software provides a convenient way to collect the data generated by the Trident’s serial output. The user can select the logging time interval. Data is written to an ASCII file that could then be imported into a spreadsheet or other application.
