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, followed by a
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.
5.3
Test Equipment and Tools Required for Calibration and
Repair
Calibration of the R1L-BIR1 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.
