Standard Performance
Measurement accuracy: The following specifications apply to operation of the CX2000
under standard operation conditions:
Temperature:
23 ± 2 °C
Humidity:
55% ± 10% RH
Supply voltage: 90 to 132 or 180 to 250 VAC
Power frequency: 50/60 Hz ± 1% Warm-up time: At least 30 minutes.
Other ambient conditions such as vibration should not
adversely affect the operation of the CX2000.
