Programmed characteristic sensor curves
Direct resistance measurement
The EL3204-0200 can be used for direct resistance measurement in three measuring ranges (n = channel 0 ... 3).
CoE 0x80n00:19 setting | Measuring range | Resolution/digit |
---|---|---|
0x101 | 0 ...6,553.5 Ω | 0.1 Ω |
0x102 | 0 ...65,535 Ω | 1 Ω |
0x103 | 0 ...240,000 Ω | 10 Ω |
Note: the way in which the EL3204-0200 measures is electrically the same with these three settings. Only the displayed resolution is changed in the firmware. The full scale value is therefore 240 kΩ for all three measurements.
Fixed sensor curves
Further programmed sensor curves in the defined measuring range can be selected individually in the CoE entry 0x80n00:19 for each channel (n = channel 0... 3).
