Effect of Operating Conditions
Ambient temperature: Variation for a temperature change of 10
°C: within ±(0.1% of rdg + 1
digit); ±(0.2% of span + 1 digit) for Cu10Ω
Voltage variation: within ±1 digit over the range of 90 to 132, or 180 to 250 VAC (for AC power
supply, frequency 50/60Hz)/10 to 32 VDC (for the subunit of a DC power supply model)
External magnetic field: variation with respect to AC (50/60Hz) and DC magnetic fields of 400
A/m: within
± (0.1% of rdg + 10 digits) Except for power monitor module: within ±15% of range
Signal source resistance: variation with respect to signal source resistance 1 k
Ω change
(1) voltage
2 V range or below: within
±10µV
6 V range or above: within 0.1% of rdg
(2) thermocouple
within
±10µV; however it must be within 100µV when burnout is specified.
(3) RTD
Variation with respect to change of 10
Ω per wire (when all wires have the same resistance
value)
Indication: within
±(0.1% of rdg + 1 digit)
Variation in indication with respect to a difference of 40m
Ω in the resistance between
conductors (max. difference between 3 wires): approx. 0.1
°C (in case of Pt100)
Mounting position
Variation when the unit is mounted horizontally on a panel: within
±(0.1% of rdg + 1 digit)
Vibration
Variation when sinusoidal vibration of acceleration 0.2m/s 2 is applied for two hours in each of
the 3 axial directions over a frequency range of 10 to 60Hz: within
±(0.1% of rdg + 1 digit)
Transportation and Storage Conditions
These refer to the environmental conditions existing during transportation and storage from the
time of shipment from the factory until commencement of use, and also during transportation and
storage in the case of a temporary period of non-use.
If the environmental conditions are specified within the specified range, the unit will not incur
permanent damage, and can be returned to a normal working condition (although re-adjustment
may be required in some cases).
Ambient temperature

Vibration
10 to 60Hz 4.9m/s 2 max
Shock
392 m/s 2 max (in packed condition)
