Input type
	Measurement range		Measurement accuracy	Input impedance
	Min.	Maks.
0...1VDC	0 V	1,1V	±0.5% (of full scale)	Approx. 11kΩ
0...10V DC	0 V	14V	±0.5% (of full scale)	Approx. 11kΩ
0...20mA DC	0 mA	25mA	±0.5% (of full scale)	Approx. 5kΩ
4...20mA DC	0 mA	25mA	±0.5% (of full scale)	Approx. 5kΩ

In the current measurement mode input impedance is should not be connected to the input terminals. Otherwise, the device will be broken down. To change the input type from voltage to a current measurement mode while the device is operating, first, leave out the voltage inputs. Then, change input type to one of the current measurement modes.

OUTPUTS
