Operating temperature limit: -10 degree C to + 60 degree C RH 35 to 85% 9. Storage temperature limit: -20 degree C to + 60 degree C RH 35 to 85% 10. Solder condition: Put the terminal about 3 mm into a tin plate with a temperature of 230 degree C. The placement time is 3.5 seconds. After this test, 7-14 items remain normal. 11. Solder temperature: hold the solder gun at 350a?? for 3.5 seconds, and the front end of the terminal is about 3mm in contact with the solder gun. After this test, items 7-14 remain normal. 12. Anti-static: use dry nylon cloth to test the transparent cover surface in the same direction for three times. Mark the pointer difference below 1/3 of the scale length, and return to zero after three seconds. 13. Light bulb specification: DC12V 12W Note: Do not put the meter in direct sunlight, and store the meter in the packing box to prevent foreign matter from entering the meterElectrical Performance1. Standard test conditions: temperature 20 degree C, humidity 70%, no difference in test results, it can also be tested under normal temperature and humidity. 2.
