Measuring a 4 to 20 mA test signal
A 4 to 20 mA test signal may be measured via the positive and test terminal without interrupting the
measurement. The minimum supply voltage of the device can be reduced by simply changing the position of
the jumper. As a result, operation is also possible with lower voltage sources. Observe the position of the jumper
in accordance with the following table.
A0011176
