User Manual
The user should exercise great care while:
•
selecting sensor in order to optimize the measurement range to the sensors output
range
•
evaluating the PRM input range for the configured measurement
•
evaluating if the resulting resolution matches the desired resolution
Important - When the channel is configured for measuring current (mA) the
user is strongly advised to make sure the input ratings of the analog channel is not
exceeded. Allowed input range for current measurements is 0 - 30 mA.
Important - Standard 0-10 V or 4-20 mA process control signaling does not
mean that IMx-M can read any possible DC voltage or current in this range. If other
voltage ranges or current ranges are utilized there may be loss of accuracy and
resolution. The specified measurement performance is only guaranteed with either
0-10 V or 4-20 mA signalling. Accuracy ±1% (±2,9% for 4-20 mA) is only fulfilled if
the complete 0-10 V or complete 4-20 mA range is utilized to reflect the
configured full scale.

When configuring for "kg/cm
2
" in the IMx-M Manager, this EU will
be displayed as "Kg/*" in the local display due to the space
constraint.
Important: Make sure that the hardware input is configured for the appropriate
sensor type (voltage source respectively 4-20 mA) as described in Analog Inputs.
