Maintenance
and Service
This section contains instructions and information to maintain your counter.
FUSE REPLACEMENT
The counter uses one fuse.
It
is located on the rear panel next to the voltage select switch.
For 1001120VAC operation use
a
l.OA slow-blow MDL type fuse.
For 220/240VAC operation use
a
0.50A slow-blow FST type fuse.
The voltage select switch should be set to the proper line voltage. To change line voltage:
1.
Be sure the counter is disconnected from the power line.
2.
With a flat edged screwdriver, rotate the voltage select switch until the arrow points to the desired
line voltage.
3.
Change to a fuse with the value specified for the line voltage selected.
NOTE:
Always be sure that the fuse is the type and value specified for, and that the voltage select switch is set
to correspond to the AC power input voltage, or the counter may be damaged.
Air circulates through the vents in the rear panel of the counter. These vents must not be obstructed or the
temperature inside the counter may increase enough to reduce the counter stability and shorten the com-
ponent life.
PERIODIC MAINTENANCE
No periodic preventive maintenance
is
required. To maintain accuracy,
it
is
recommended that the counter
be recalibrated every six months.
Do not attempt repair or disassembly of the Microwave
Converter or Time Base Oscillator Assemblies. Contact
EIP or your sales representative.
