Model 545A
DATE CODE
The year and week of manufacture are stamped on the circuit board. Example: "5-24" would indicate 24th Week of
1975. There is no serial number.
SERIES CODE
A 4-digit series number is also stamped on the circuit board. This number should match the series number on the title
page of this manual. If the board series number differs from the manual series number, there are other differences
between the manual and the Logic Probe. These differences are covered by MANUAL CHANGES sheets included
with the manual. The MANUAL CHANGES sheet should have a series number matching the board. If it does not, ask
your Hewlett-Packard representative for a MANUAL CHANGES sheet with the matching series number. This manual
covers probes with several series numbers. Each item in the manual affected by a different series is labelled with the
appropriate series number.
UNPACKING
If the shipping package is damaged, ask that the carrier's agent be present when the package is opened. Inspect the
Logic Probe for obvious physical damage (dents, scratches, etc.) If the Logic Probe is damaged or fails to meet speci-
fications, notify the carrier and nearest Hewlett-Packard Sales and Service Office immediately. (Sales and Service
offices are listed at the back of this manual). Retain shipping package and packaging material for carrier's inspection.
The Sales and Service office will arrange for replacement of your Logic Probe without waiting for a claim against the
carrier to be settled.
GRABBER SQUEEZE CONNECTORS
Three grabber squeeze connectors are supplied with the 545A. Two grabbers may be pressed on the two ends of the
545A power cable for power supply connections. One grabber may be pressed on the end of the short ground wire for
ground connections. Use of the grabber is shown in Figure 1.
