Abrasive agents, strong detergents, or other solvents may damage the probe. Always ensure that the input receptacles are free of debris before connecting accessories. CALIBRATION INTERVAL To guarantee accurate performance, you should have the probe calibrated every 12 months. Avoid exposing the probe to extreme mechanical shock and excessive bending of the cable because these may alter the calibration. SERVICE STRATEGY The AP034 circuits utilize fine pitch surface mount devices; it is, therefore, impractical to attempt repair in the field. Defective probes must be returned to a LeCroy service facility for diagnosis and exchange. A defective probe under warranty will be replaced with a factory refurbished probe. A probe that is not under warranty can be exchanged for a factory refurbished probe. A modest fee is charged for this service. The defective probe must be returned in order to receive credit for the probe core. TROUBLESHOOTING If the probe is not operating properly, the problem may be the way in which it is used. Before assuming the probe is defective, perform the following troubleshooting procedures. A. Trace Off Scale This is typically caused by improper offset setting, or by an input signal that exceeds the probe differential or common mode range. Perform the following: 1. Remove the input signal from the probe, return the offset to zero, and Autobalance the probe. Does the trace return to approximately the center of the graticule? If not, proceed to step 7.
