Low Power Resistance Measurement Function
*: When using external triggering, open-terminal voltage is limited to 20 mV maximum from when INDEX goes
High until the next trigger input.

HIOKI 9451 (PT500 (at 25
°C))
Accuracy
*1: Accuracy is in combination with 9451 TEMPERATURE PROBE.
Accuracy of instrument alone is ±0.2°C for 6 months (±0.3°C for 1 year).
Add temperature coefficient ±0.02/°C to above accuracy for ambient
temperature ranges 0 to 18 and 28 to 40°C.
Temperature measurement (analog input)
Accuracy 1-Year
*2: Temperature accuracy conversion method (Only 3541 instrument)
Add temperature coefficient (±0.1% rdg ±0.3 mV)/°C to above accuracy for
ambient temperature ranges 0 to 18 and 28 to 40°C.
1-year accuracy (23 ±5°C)
