DTG-RTD100 Design for CE Conformity

Section 7 - DTG-RTD100 Design for CE and UKCA Conformity

All models of the DTG-RTD100 Digital RTD Meter have been designed to meet
requirements as outlined in European Community EMC Directive and UK
Electromagnetic Compatibility Regulations 2016 to standard EN 61326-2-1: 2013
for analog output cable length up to 98 feet or 30m. Some loss of performance
may be observed in the presence of strong RF electromagnetic fields. For a field
strength of 10V/m in the 400 MHz to 1 GHz range, reading errors of up to ±5°C
may occur.

7.1 DTG-RTD100 Analog Output Grounding

The analog output cable is supplied with accompanying grounding hardware.
The figures below specify the wiring and procedure required to properly ground
your DTG-RTD100 unit.
7-1
In order for this instrument to conform to the requirements of
the European Union, the RTD input cable must not exceed 3m
in length. The instrument can function with longer lengths
than 3m, but may become susceptible to error or damage
due to Electromagnetic noise interference.
