Maintenance
Note
When servicing the meter, use only the replacement parts specified.
Introduction
Chapter 6 provides the information necessary for the user to perform basic maintenance.
Users should not attempt to perform maintenance not described in this chapter. Qualified
service personnel should refer to the 45 Service Manual (P/N 856042) for complete main-
tenance, service, and calibration procedures.
Cleaning
WWarning
To avoid electrical shock or damage to the meter, never get
water inside the case.
Caution
To avoid damaging the meters housing, never apply solvents to
the meter.
If the meter requires cleaning, wipe it down with a cloth that is lightly dampened with
water or a mild detergent. Do not use aromatic hydrocarbons, chlorinated solvents, or
methanol-based fluids when wiping down the meter.
Line Fuse
The meter has a T 125mA, 250V, (Slow blow) line fuse in series with the power supply.
This fuse is located on the rear panel. To replace this fuse, unplug the line cord and
remove the fuse holder with fuse as shown in Figure 6-1. The meter is shipped with a
replacement fuse.
W Warning
To avoid electric shock or fire, do not use makeshift fuses or
short-circuit the fuse holder.
