The equipment 0.05 single-phase AC/DC standard source, can verify magnitude 0.2 and the following AC/DC voltmeter, ammeter, frequency meter, resistance meter.
The source signals by using DSP and 16-bit high-speed analog-to-digital converters of controllable sine wave, the distorted wave signal source.
The equipment comes with RS-232 interface, can be connected with PC to a semi-automatic verification system.
It has precise interface and multi-functions including verification, storage and query.
Features |
-
It can be semi-automac or manual inspecon of analog mul meter, clamp type current meter, all kinds of electric meter, (voltmeter, ammeter, frequency meters, resistance meter) basic error.
- The equipment can be generated with 2-31 harmonic wave, harmonic number, order, amplitude and harmonic phase of fundamental wave can be programmed.
- Power amplifier working frequency range is 40Hz-1KHZ, has a good linear. Current amplifier is constant current source; voltage amplifier is constant voltage source. Because of light weight, this device is more suitable for field use.
- With RS-232 interface, this device is controlled by PC through the PC soware (oponal), can be automac or manual inspecon, and the results are processing and management
- Has a non-volale memory, it can store 500 pieces of the raw data of tested meter, for access and upload.
