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.
