Effects of Operating Conditions
The specifications below apply when the integration time is 16.67 ms or more.
Warm-up time:
At least 30 minutes after power-up
Effects of ambient temperature:
The effect received by changes in 10 degree increments of the
ambient temperature is ±(0.05% of rdg. + 0.05% of range) or less.
However, for Cu10 Ω: ±(0.2% of range + 1 digit)
Effects of power fluctuation:
Meets the accuracy specifications for AC power supply in the
range 90 to 132 V and 180 to 250 V
Effects of magnetic field: The fluctuation in external magnetic fields for AC (50/60 Hz)
400 A/m is ±(0.1% of rdg. + 10 digits) or less
Effects from the signal source resistance: Effect from fluctuation in DC voltage signal
source resistance of 1 kΩ
1 V range or less ±10 µV or less
2 V range or higher ±0.15% of rdg. or less
RTD: Fluctuation from 10 Ω change per line
1000 Ω, 100 Ω types: ± 0.1°C or less
Other than 1000 Ω, 100 Ω types: ± 1.0°C or less
Resistance: Fluctuation from 10 Ω change per line: ±1 digit or less
Effect of position: Horizontal with the feet at the bottom is the rule.
Effects of vibration: The fluctuation that results by applying a sinusoidal vibration
along all three axes at a frequency between 10 to 60 Hz and an
acceleration of 0.2 m/s
2 is ±(0.1% of rdg. + 1 digit) or less
