Effects from Operatng Condtons
Item Specfcatons
Ambient temperature (applies when the A/D integration time is 16.7 ms or greater)
DC voltage, TC range With temperature variation of 10°C: ±(0.1% of rdg + 0.05% of range) or less
* Excluding the reference junction compensation error
RTD range ±(0.1% of rdg + 2 digits) or less
Power supply fluctuation With a fluctuation within 90 to 132 V and 180 to 250 VAC (50/60 Hz): Accuracy specifications are
met.
With a fluctuation of ±2 Hz of the rated power frequency (supply voltage 100 VAC): Accuracy
specifications are met.
Magnetic field AC (50/60 Hz) and 400 ADC/m fields: ±(0.1% of rdg + 10 digits) or less
Signal source resistance
DC voltage range With a variation of source signal resistance + 1 kΩ:
200 mV range or less: ±10 µV or less
2 V range or higher: ±0.15% of rdg or less
TC range With a variation of signal source resistance +1 kΩ: ±10 µV or less
RTD range (Pt100) With a variation of 10 Ω per wire (same resistance for all three wires): ±(0.1% of rdg + 1 digit) or
less
With a maximum difference of 40 mΩ between wires: Approx. 0.1°C
Effects of vibration Effects from a sinusoidal vibration along all three axes at a frequency between 10 to 60 Hz and
an acceleration of 0.2 m/s 2 : ±(0.1% of rdg + 1 digit) or less
Mscellaneous
Item Specfcatons
Memory backup A built-in lithium battery backs up the settings and runs the clock
Battery life: Approximately 10 years (at room temperature)
Clock With a calendar function
Time can be synchronized by using an external contact (remote control function, option).
Clock accuracy: ±10 ppm, excluding the delay at power-on (1 s or less)
