GENERAL DESCRIPTION

The PAXLT is a versatile meter that accepts a variety of thermocouple and 

RTD inputs and provides a temperature display in Celsius or Fahrenheit. The 

readout conforms to ITS-90 standards, with 1° or 0.1° resolution. The 5-digit 

display has 0.56" high digits with adjustable intensity. Backlight overlay labels 

for °F and °C are included.

The meter features a Maximum and Minimum reading memory, with 

programmable capture time. The capture time is used to prevent detection of 

false max or min readings which may occur during start-up or unusual process 

events. Either value can be displayed if desired. The display can be toggled 

manually or automatically between the selected values.

Other features include thermocouple cold junction compensation, display 

offset and a programmable user input to perform a variety of meter control 

functions. Two setpoint outputs are provided, each with a Form C relay. Output 

modes and setup options are fully programmable to suit a variety of control 

requirements.

The PAXLT can be universally powered from a wide range of AC or DC 

voltage. The meter has been specifically designed for harsh industrial 

environments. With a NEMA 4X/IP65 sealed bezel and extensive testing to meet 

CE requirements, the meter provides a tough yet reliable application solution.
 

SAFETY SUMMARY

All safety regulations, local codes and instructions that appear in this and 

corresponding 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 meter 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 meter
