*After 20 min. warm-up. Accuracy is specified in two ways: Accuracy over an 18
to 28 °C and 15 to 75% RH environment; and Accuracy over a 0 to 50 °C and 0 to
85% RH (non condensing) environment. Accuracy specified over the 0 to 50 °C
operating range includes meter tempco and ice point tracking effects. The
specification includes the A/D conversion errors, linearization conformity, and
thermocouple ice point compensation. Total system accuracy is the sum of meter
and probe errors. Accuracy may be improved by field calibrating the meter readout
at the temperature of interest.
** The accuracy over the interval -270 to -200 °C is a function of temperature,
ranging from 1 °C at -200 °C and degrading to 7 °C at -270 °C. Accuracy may be
improved by field calibrating the meter readout at the temperature of interest.
*** These curves have been corrected to ITS-90.

UNITS LABEL KIT (PAXLBK) - Not required for PAXT
Each meter has a units indicator with backlighting that can be customized
using the Units Label Kit. The backlight is controlled in the programming.
Each PAXT meter is shipped with °F and °C overlay labels which can be
installed into the meter’s bezel display assembly.
EXTERNAL CURRENT SHUNTS (APSCM)
To measure DC current signals greater than 2 ADC, a shunt must be used. The
APSCM010 current shunt converts a maximum 10 ADC signal into 100.0 mV.
The APSCM100 current shunt converts a maximum 100 ADC signal into 100.0
mV. The continuous current through the shunt is limited to 115% of the rating.
PROGRAMMING SOFTWARE
The Crimson software is a Windows based program that allows configuration
of the PAX meter from a PC. Crimson offers standard drop-down menu
commands, that make it easy to program the meter. The meter’s program can
then be saved in a PC file for future use. A PAX serial plug-in card or PAX USB
programming card is required to program the meter using the software. Crimson
can be downloaded at www.redlion.net.
