Main characteristics (1). Multifunctional A/D dual-display meter combining a 4 1/2 bit D meter and a pointer A meter of 0.5 grade calibration accuracy (2). Wide-and multi-range measurement options (3). Extra-strong overload capacity to protect the meter in case of any incorrect wiring or operation during experiment and measurement, without affecting power connection to other parts (4). Automatic sound-light alarm when overloaded; automatic retrieval of measurement after overload is eliminated (5). Automatic record of overload times to facilitate examination and check-ups during teaching (6). The AC wattmeter has voltage display, current display, single and combined overload display to facilitate troubleshooting (7). Wide frequency response (50KZ-20KHZ) for the AC meter (8). The sub-ideal meter does not change the circuit state when connected to the circuit, and can greatly increase the experimental test accuracy. (9). Reading latch functions (10). With independent protection system and independent stabilized power supply, independently workable away from experiment bench (11). Variable ranges for continuous circuit measurement. No need to disconnect and reconnect power supply (12). With data communication interfaces
