CMRR: >100 dB (50 or 60 Hz)
Note 3:
The excitation power supply for RTD measure is 0.2mA, and each position has 4-wire, 3-wire and 2-wire methods. The accuracy
is as follows:
(1) The accuracy data given in the table is based on the 4-wire mode;
(2) The accuracy of the 3-
wire method is 10mΩ more than the accuracy of the 4
-wire mode;
(3) The accuracy of the 2-
wire method is 50mΩ more than the accuracy of the 4
-wire mode.
Note 4:
Minimum threshold voltage for frequency and pulse measure: 2.5V
Note 5:
Supported frequency units: Hz, kHz, MHz, CPM, CPH, s, ms, us;
Note 6
: Optional rising edge or descending edge trigger mode for pulse measurement.
