MAINTENANCE
5.1
Inspection
These units should be inspected semi-annually. Cables
should be periodically inspected to make sure they are in
good condition. Check that the pushbutton and rotary
switches operate smoothly. Check all four binding posts to
ensure that they operate smoothly. Check that the case
opens and closes with no binding.
5.2
Cleaning
The instrument should be cleaned periodically, as is
necessary, using mild soap and a damp cloth both followed
by second damp rinsing cloth.
Clean the LCD window using a soft cloth moistened with
water or "Windex" type window cleaner.
DO NOT
use
common paper towel products as some brands may contain
fibers which could scratch the display window.
DO NOT
apply significant pressure to the LCD window as it could
separate from the front panel.
DO NOT
use alcohol,
solvents, or harsh chemicals to clean the LCD window.

MΩ, 100 MΩ, 1 GΩ, 10 GΩ, and 100 GΩ with accuracy of
0.1% or better.
A standard digital voltmeter: 3 ½ digits minimum, with 19.99
and 999 V ranges, accuracy of 0.02% of reading or better.
