set the on screen range close to the expected measurement value. Based on the range chosen, the unit determines the
sense current and voltage range to use for measurement.
3.4.5 Current Measurement
The recorder includes the option to convert sensed voltage across a shunt or sense resistor into a current reading. From
the “Home” screen, open the “Channels” menu. The “Type” row shows the current function per channel. Press the
square in the “channel” column and “Type” row to open the configuration dialog for the function type. See
Select the “Current” menu option. The window will change to show a button listing the current shunt value. To change
the value, press the button and a dialog for setting the shunt value will open. See
. Set the value and unit
and press the green check mark to confirm the setting and the screen will return to the previous menu.
To wire the circuit for current measurement, connect the “+” and “-” terminals to the current shunt. Also, set the
current range in the “Channels” window appropriately. Use either an external resistance or a shunt (ref 902406500: 50
Ω
).
