1. Summary
The TK3100 miniature installed single-phase standard energy meter is a standard energy meter with the same physical dimensions as conventional installed single-phase energy meters. It is specially used to verify the AC energy meter calibration devices or energy measurement calibration units in AC energy meter automated test system. It can complete testing items such as basic error and multi-channel output consistency.
2. Features
• Accuracy class 0.02 and class 0.05 are optional.
• Voltage measurement range: 50 V ~ 288 V.
• Current measurement range: 5 mA～120 A.
• Voltage and current support fully automatic switching of range.
• Phase measurement uncertainty typical value:0.006°.
• Lithium battery power supply to avoid the impact of PT power taking on measurement.
• The battery can last for 8 hours and the charging time is less than 2 hours.
• Optional manual charging or automatic charging. The automatic charging standard version requires an optional charging system.
• Supports RS485 communication and RS232 communication.
• An external display screen (optional) can be connected to display the measured power.
