TIF900 Fig. 5: Connection of the instrument’s terminals during calibration procedure Press GO to perform the measurement Press and hold ZERO key for 2s. The instrument resets the resistance of the MODE cables, the symbol ZERO is displayed PEAK 5. The measured value is stored by the instrument and used as offset (which means it’s deducted from all continuity tests performed) until a new pressing of the ZERO key for 2s that voids the calibration. -
