Calibration
Scale without signal or calibrate with
signal source
Calibration
Range
User programmable over entire range
of meter
Input
Impedance
Voltage range: greater than 1 MΩ,
Current range: 50-
100 Ω, varies with
resettable fuse impedance
Input
Overload
Protected by automatically resettable
fuse
HART
Transparency
The meter does not interfere with
existing HART communications; it
displays the 4-20 mA primary variable
and it allows the HART communications
to pass through without interruption.
The meter is not affected if a HART
communicator is connected to the loop.
The meter does not display secondary
HART variables.
