[0063] Step 1: Connect the multi-function output port of the meter to be calibrated to the corresponding port of the meter calibration station, switch the meter calibration station to the multi-function test day timing error, set the test time to 1 minute, and the cycle to 2 times. Power on the calibration table.
[0064] Step 2: After waiting for 2 minutes, the meter calibration software of the meter calibration station counted the results of the 2 daily timing error tests, and also gave the average value.
[0065] Step 3: The software calculates the compensation value according to the formula "compensation value = error value * 10 / 0.0864", clicks to correct, and writes the compensation value into the register of the electric energy meter.
[0066] Step 4: Check the average value of the daily timing error of each calibrated watch. If the average value is within 0.06 seconds / day, it means that the daily timing error has been adjusted. If there is a table with a large average,...
