- Input type (Universal input) : ※See the Input Range Code for the input range.
1) Temperature, DC current, DC voltage (low) input group
Thermocouple: K, J, R, S, B, E, N, T, W5Re/W26Re, PLII, U, L
RTD: Pt100 or JPt100 (3-wire type)
DC voltage (low): 0 to 10mV, -10 to 10mV, 0 to 100mV, -100 to 100mV, 0 to 1V
DC current input: 0 to 20mA, 4 to 20mA
2) DC voltage input (high) group
DC voltage input (high): -1 to 1V, 0 to 5V, 1 to 5V, 0 to 10V
- Sampling time: 0.25 sec.
- Measurement accuracy : ±(0.1% of displayed value+1 digit) ※Depends on the input and the range.
- Hold function
1) Peak hold: Maximum measured value is retained.
2) Bottom hold: Minimum measured value is retained.
※The stored value can be reset by key operation, external contact signal, or communication.
※When the instrument is turned off, the hold values (peak/bottom) are not backed up.
