Analog inputs
Analog input applications
You can use an analog input to monitor an analog flowmeter to monitor how much
water flows through a pipe.
For analog input operation, your meter takes an analog input signal and provides the
resulting scaled value.
Your meter’s analog I/O option modules can measure either low voltage or current
using standard analog transducers such as 4 - 20 mA current transducers.

Analog input voltage and current mode
You can set the analog input’s mode for voltage or current sensing.
In current mode, the analog inputs have a low input resistance while the meter is
powered on, and a high input resistance when the meter is powered off. In voltage
mode, the analog inputs have a high input resistance regardless of whether the meter
is powered or not.
NOTE: When unpowered, your meter’s analog inputs act like they are in voltage
mode (high input resistance).
When connected to a current output transducer, this high resistance can create a high
voltage. Standard (i.e., 4 to 20 mA) current transducers have open circuit protection
and are able to handle a high input resistance; however, if non-standard transducers
are used high voltages may be generated. Your meter’s analog input has circuitry to
limit this voltage, but it may not be sufficient with a very high-power current source.
NOTICE
EQUIPMENT DAMAGE
Failure to follow these instructions will result in equipment damage.
Ensure the analog input is configured for the correct voltage or current mode
before connecting or activating the current transducer.
Do not exceed the device’s ratings for maximum limits.

Analog input behavior
Analog inputs may show a value below zero scale if an open circuit is detected on the
input port.
