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.
