CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Input: Check that the input voltage is within 0 – 100% of
full-scale.
If the thermocouple/RTD or its extension wires are bro-
ken, the output goes over 100% (below 0% with down-
scale) due to the burnout function. Check leadwires in
such a case.
3) Output: Check that the load is within the permissible
limit including wiring resistance.
Load Resistance (Ω) =
Supply Voltage (V) – 9 (V)
0.023 (A)
(including leadwire resistance)

PC CONFIGURATOR SOFTWARE
To calibrate the signal to match with a receiving instrument
or to change the factory-set configurations, use the PC Con-
figurator software installed on a Windows PC via a HART
modem connected to the PC.
The PC Configurator software is downloadable at M-Sys-
tem’s web site: http://www.m-system.co.jp

USING THE HART COMMUNICATION
Refer to the HART Setup Manual (EM-7501-B) for setting
up the unit using the HHC. For operating an HHC (Hand-
Held Communicator), refer to its instruction manual.
