CALYS 1500
The following ranges are available:
Range
100 mV
Resolution
1 µV
Input impedance
> 1 G
The DC voltage to be measured is connected between the V and COM terminals.
B.2.2
Measuring current
Display the MEASUREMENT MENU dialogue box:
Select the Idc measurement function then the correct range of measurement using the function and navigation
keys.
Confirm with ENTER.
Depending on the range selected, several modes of measurement are available:
Range
100 mA
Resolution
0.1 µA
Input impedance
< 30
Loop power supply
No
Set to scale
No
If loop power supply is on, the connection is made between terminals 4-w and mA.
In this case, the CALYS 1500 supplies a passive transmitter with 24 V and at the same time measures the current
established by the transmitter.
If the loop power supply is off, the connection is made between terminals mA and COM.
