Installing the Test Set
1. Preparing for Use
Providing Adequate Ventilation
Cooling holes are located on the bottom of the instrument cover and the rear panel
of the instrument. Do not allow these holes to be obstructed as they facilitate air
flow through the product.
CAUTION Ventilation Requirement: When installing the product in a system cabinet, the
convection into and out of the product must not be restricted. The ambient
temperature (outside the cabinet) must be less than the maximum operating
temperature of the product by 4°C for every 100 watts dissipated in the cabinet. If
the total power dissipated in the cabinet is greater than 800 watts, then forced
convection must be applied.
Instructions for Cleaning
For cleaning the surface of the instrument, gently wipe with soft, damp cloth.
Replacing the Line Power Fuse
The line power fuse holder is located on the right side of the Agilent E6392B’s rear
panel. Before replacing the fuse, disconnect the Agilent E6392B’s line power. To
replace the fuse, use a small flat blade screwdriver to push in on the fuse cap and
rotate it counterclockwise. Remove the fuse cap and replace the fuse with the
appropriate type. Reinstall the fuse cap and apply power.
The type and rating of this fuse are as follows.
UL/CSA type, time delay, 2 A, 250 Vac
Warm-Up Time
In order for the Test Set to meet its specifications, allow the Test Set to warm up
for 30 minutes after being turned on before attempting to make any measurements.
