OUTPUTS
Auxiliary power supply
12V DC, max. 50mA (unregulated) or 8V DC, max. 50mA (regulated) or 5V DC max. 50mA (regulated)
In the current measurement mode input impedance is 5
W.
Therefore, in the current measurement mode, any voltage input
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.
EI741A must not be used in location where measurement category is II, III or IV.
* 72x72mm sized.
* 4 digits display.
* Easy to use by front panel keypad.
* Display scale can be adjusted between -1999 and 4000.
* Decimal point can be adjusted between 1. and 3. digits.
* Measurement unit can be displayed.
* Selectable four different standard input types (0-20mA, 4-20mA, 0-1V, 0-10V)
* User can calibrate the device according to his/her own specified input type.
* Sampling time can be adjusted in four steps.
* Maximum and minimum measurement values are registered.
* The maximum or the minimum values can be hold on the display.
* Current and voltage calibration can be made..
* Parameter access protection on 3 levels.
* Easy connection by removable screw terminal.
