The following schematic diagram shows the relative error of the tested meter is-0.0023 %.
Connect the sampler that matches to each tested meter to the photo electrical input "       "   of  HPU-8001. The HPU-8001 displays the error of each tested meter.
If the meter has pulse output, break the connection between infrared collector and the photo electrical input "    "of HPU-8001. Use special cable to connect the pulse output of the calibrated meter with the photo electrical input "    "of HPU-8001.connect the red clip to the +5V terminal of pulse and the black clip to 0V.
If HPU-8001 works abnormally, the user can press HPU-8001"reset"botton, and HPU-8001 will regain the normal program automatically. In the process of the bench test,it you want HPU-8001calculate again,you can press "reset" button.
