MAINTENANCE
SECTION 5
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 switches turn smoothly.
Check all four binding posts to ensure that they operate
smoothly.
No other maintenance is required, other than to keep the
battery charged through power line operation. Charging
should be done for at least 14 hours after long periods
(several months) of storage or after considerable use on
battery power.
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 as it could separate from the
front panel.
DO NOT
use alcohol, solvents, or harsh
chemicals to clean the LCD window.
5.3
Test Equipment and Tools Required for Calibration
and Repair
Calibration of the R1L-B is recommended on a yearly basis,
and is done at a temperature of 23 °C ± 1 °C. To obtain
best results, keep the unit at 23 °C ± 1 °C for at least 8
hours, and allow it to warm up for 30 minutes before
making any adjustments.
