7.3.7 RTD Input Measuring
Accuracy
1. Use the front-panel Set Relay\Relay
Elements\RTD Configuration function or serial
port SHOW command to view the input RTD
Type setting for each RTD input. Connect a
variable resistance to each RTD input in turn.
The temperatures given in Table 7.8 on
page 107 – Table 7.11 on page 108 are based
on the RTD type and the value of the
resistance. Referring to these tables, change
the resistance applied to each input until the
appropriate temperature is displayed.
2. Use the front-panel Meter Values\Thermal &
RTD Data function or serial port METER T
command to view the present temperature
measured by the relay RTD input. The
temperature displayed should be ± 2°C or
± 4°F from the temperature represented by
the variable resistance.
