Operation environment
Temperature: －*0℃ ～ *0℃, humidity: ≤*0%, Altitude: ≤***0m
Dimension&Weight
Dimension: **0mm × **0mm × **0mm Weight: ≤*0Kg
Working condition
1. Input voltage: **0VAC±*0%,
rated frequency:*0/*0Hz (range: ****5Hz)
2. The quality of input power supply may influence testing result
of CT/PT analyzer.
3. The analyzer should be supplied by power supply socket which
have ground protection. If ground protection connection is not good
or power supply is not isolation connection with ground, the
analyzer can still work but we could not promise the security.
4. Environmental temperature is *3℃±5℃.
5. The assured value is valid within one year after factory
calibration.
