: to show HART compatibility.
When the values measured are near the lower limit of the range (0 mA or 4 mA) a small variation in the values
measured translates into a more significant variation for the converted values (in %) because of the square law
nature of the scaling.
B.2.3
Measuring resistance
Display the MEASUREMENT MENU dialogue box:
Select the Idc measurement function then the correct measurement range using the function and navigation
keys.
Confirm with ENTER.
The following ranges are available:
Range (1)
400 Ohm
3600 Ohm
50 KOhm
Auto
Resolution
1 mOhm
10 mOhm
0.1 Ohm
--
Measurement current
0.2 to 0.45 mA
0.2 to 0.45 mA
10 µA à 25 µA
(1) 50 KOhm range only for channel 1
To carry out a correct resistance measurement with 3 wires, the 3 conductors used must be:
of the same length,
of the same diameter,
of the same type of metal.
The CALYS 1500 displays an icon showing the connections used (
for 2 wire,
for 3 wire or
4 wire) to
make the measurement. The wiring arrangement is automatically detected by the calibrator.
