Step S265: read tested table register charge value record；
Step S266: the slow liter of voltage is set and delays fall change frequency；
Step S267: voltage is set and delays eustasy speed；
Step S268: minimum minium operation voltage and the maximum operating voltage upper limit of voltage up-down change are set；
Step S269: setting and the number of times of electric energy meter communication and communication time interval, acquiescence receives electric energy meter return value and starts for 0 second
Communication next time；
Step S2610: repeatedly reading tested table register charge value, recording impulse sends number simultaneously；
Step S2611: whether change according to depositor charge value before and after test and whether have pulse to send automatically in process of the test
Judge conclusion (of pressure testing)；
Step S2612: in recovery temperature control box, room temperature is reference temperature, off-test.
