The following are the specific steps of self-checking.StepsVFD displayDetailsAfter the electronic load power onSYSTEM SELF TESTVx. xSystem self-checking and show version number of the softwareAfter about 1 secondEPROM ERRORIf the EEPROM damaged or lost the last load condition presented in EEPROM, the VFD will show prompt message(about 2S).ERROR CAL. DATAIf lost the calibration data presented in the EEPROM, the VFD will show the prompt message(about 2S) as below.If show error, then after about 2 secondsxxxxxxxV xxxxxxxAxxxxxxxW xxxxxxxXVFD will show the actual input voltage, current, power, parameter settings and present situation.3.2 If the load can’t startYou can use the following ways to solve the problems when you start the load.1) Check the power cord is connectedFirst check the power cord is connected, the load is being power supply, the power switch is started.2) Check the load voltage setting The load working voltage is 110V or 220V, checking your load voltage setting is matching with the power supply voltage.3) Check if the fuse of the load is burnt.If the fuse of the load is burnt, please replace the fuse specifications from the table below.TypeFuse specifications (110VAC)Fuse specifications (220VAC)M9710TO. 5A 250VTO. 3A 250VM9711TO. 5A 250VTO. 3A 250VM9712TO. 5A 250VTO. 3A 250VM9712BTO. 5A 250VTO. 3A 250VM9712CTO. 5A 250VTO. 3A 250VPage 53.3 Front panel and back panel introductionThe front panel of M97 series electronic load is shown below.① The top half of the panel is a black VFD display screen and a switch.② The bottom half of the panel from left to right are 0~9 number keys, ESC, menu, move up(▲) and down(▼) keys, input and output terminals.The back panel of M97 series electronic load is shown below.① the electric current from 0 to full scale, corresponding 0~10V output; can connect the oscilloscope to observe
