If your ETCR Test Equipment displays “Err”, shows big error results, or the results are unstable, the possible causes include: * Insufficient battery capacity: Replace the batteries. * Contaminated jaw contact surface: Clean the surface. * Poor jaw closure: Trigger the clamp several times and then reboot. * Defective circuit component: Replace the PCB. * Incorrect measurement steps: Study the manual and follow it.
