UNPACKING
If the shipping package is damaged, ask that the carrier's agent be present when the package is
opened. Inspect the Logic Pulser for obvious physical damage (dents, scratches, etc.). If the Logic
Pulser is damaged or fails to meet specifications, notify carrier and nearest Hewlett-Packard Sales
and Service office immediately. (Sales and Service offices are listed at the back of this manual.) Re-
tain shipping package and packaging material for carrier's inspection. The Sales and Service office
will arrange for replacement of your Logic Pulser without waiting for claim against carrier to be
settled.
POWER SUPPLY
The power leads are connected to the power supply of the logic being pulsed (3 to 18V). Reverse
polarity and excess voltage protection are provided. The red power lead is connected to the positive
side of the power supply.
OUTPUT GROUND CABLE
A connector for the ground cable provided is located at the tip of the Logic Pulser. When maximum
current output is desired, use the ground cable supplied with the Pulser to make the common return
path as short as possible. Current pulses from the Pulser can be more than 650 mA. The ground cable
reduces the IR drop and the lead inductance.
