GENERAL DESCRIPTION
The Pax Lite Thermocouple Meter accepts inputs from standard
thermocouples and precisely linearizes them. A full 4-digit display
accommodates a wide range of temperature inputs. The unit automatically
compensates for cold junction, NBS linearity and the meter’s zero and span.
The meter features a readout choice of either Fahrenheit or Celsius with 0.1
or 1 degree resolution. English Style display prompts and front panel buttons aid
the operator through set-up and operation. With a few simple steps the unit can
be used as a millivolt meter by selecting “
” for thermocouple type. This
mode is useful in monitoring and displaying the actual voltage produced at the
thermocouple probe junction and as an aid in troubleshooting for a faulty
thermocouple probe.
The meter provides a Peak (HI) and Valley (LO) reading memory with
selectable capture delay time. The capture delay is used to prevent detection of
false Peak or Valley readings that may occur during start-up or unusual process
events. The Peak and Valley readings are stored at power-down to allow
monitoring the process limits over any length of time (shifts, days, etc.).
Programmable digital filtering enhances the stability of the reading. All set-
up data is stored in EEPROM, which will hold data for a minimum of 10 years
without power. The meter has several built-in diagnostic functions to alert
operators of any malfunction.
Extensive testing of noise interference mechanisms and full burn-in makes
the indicator extremely reliable in industrial environments. The front bezel
meets NEMA 4X/IP65 requirements for wash down applications.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
literature or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired. Do not use this unit to directly
command motors, valves, or other actuators not equipped with safeguards. To
do so, can be potentially harmful to persons or equipment in the event of a fault
to the unit.
