Why is my ETCR Test Equipment incapable of resistance measurement?
- E
  Erica BanksAug 22, 2025
  If your ETCR Test Equipment is incapable of resistance measurement, it could be due to these reasons: * Insufficient battery capacity: Replace the battery when the 'Low battery' mark is displayed on the LCD. * Poor jaw closure, indicating 'jaw-open' symbol on LCD: Trigger the clamp several times and then reboot. * Contaminated jaw contact surface: Clean the surface. * Without self-calibration before test: Reboot and follow the manual, conduct measurement after self-calibration is finished. * Defect of circuit component: Check the above points first. If there is no problem, replace the PCB, and do re-adjustment.
