Ammeters1.Include a current transformer2.Please try not to install the meter and current transformer around the high temperature strong magnetic fieldand large transformer otherwise the accuracy will be affected.3.In order to obtain a higher precision measurement it is recommended to "preheat for 5 minutes" beforeadjusting the calibration.4.Since the 24V battery charge full of floating voltage may be over 30V so "no" recommended direct use it.5.When you select range not the larger the better. the larger the range the larger the error it is recommendedthat it is 1.5 or 2 times as large as the actual test value.6.This meter and CT have been calibrated by the "one to one". Please don't mix it up when you use it in the later period. If mixed you need to recalibrate it.Technical Parameters:Supply voltage:DC4-30V(Note:The maximum input voltage can not exceed 30V or be burnt.)
