Item Specfcatons
Ambient temperature With temperature variation of 10°C:
Measurement: ±(0.1% of rdg + 1 digit) or less
Recording: Measurement fluctuation + ±0.2% of the recording span or less
* Excluding the error of reference junction compensation
Power supply fluctuation With variation within 90 to 132 V and 180 to 264 VAC (50/60 Hz):
Measurement: ±1 digit or less
Recording: ±0.1% of the recording span or less
With variation of ±2 Hz from rated power frequency (power supply voltage 90 to 132, 180 to
264 VAC):
Measurement: ±(0.1% of rdg + 1 digit) or less
Recording: Same as the measurement fluctuation
Magnetic field AC (50/60 Hz) and DC 400 A/m fields:
Measurement: ±(0.1% of rdg 10 digit) or less
Recording: ±0.5% of the recording span or less
Input source resistance
DC voltage range With variation of +1 kΩ:
Ranges of 200 mV or less: Within ±10 µV
Ranges of 2V or more: ±0.1% of rdg
TC range With variation of +1 kΩ: ±10 µV or less
RTD range With variation of 10 Ω per wire (resistance of all three wires must be equal):
Measurement: ±(0.1% of rdg + 1 digit) or less
Recording: Measurement fluctuation + ±0.1% of the recording span or less
With maximum difference of 40 mΩ between wires: Approx. 0.1°C (for Pt100)
Mounting position With a backward tilt of 30° or less
Measurement: ±(0.1% of rdg + 1 digit) or less
Recording: Indication fluctuation + ±0.1% of the recording span or less
Vibration When a sinusoidal vibration along all three axis at a frequency between 10 to 60 Hz and an
acceleration of 0.2 m/s 2 is applied for 2 hours
Measurement: ±(0.1% of rdg + 1 digit) or less
Recording: Indication fluctuation + ±0.1% of the recording span or less
Other Specfcatons
Item Specfcatons
Clock With a calendar function
Accuracy of clock ±100 ppm, excluding a delay (of 1 second, maximum) caused each time the power is turned on.
DST The date/time for switching between standard time and DST can be specified.
Memory backup A built-in lithium battery backs up the setup parameters and runs the clock
(battery life: approximately ten years at room temperature).
Key lock function Password for releasing the key lock can be set.
Key lock items RCD key, MENU key, DISP MENU key, FEED key, and function under the FUNC key (Alarm ACK,
computation start/stop, print, message, printout buffer clear, periodic printout reset, and pen or
ribbon cassette exchange)
Internal light Lights up the recording area of the chart paper. Uses a dedicated LED.
Noise Machine Noise Information Ordinance 3.GSGV, Jan 18, 1991
Maximum noise level: 60 dB (A) or less (complies with ISO7779)
