Other Considerations
Readings on the sensitive voltage, current and resis-
tance ranges may sometimes be different than calcu-
lated values. Thermo-electric or electro-chemical re-
actions can sometimes generate voltage (and current)
in a circuit due to elevated temperatures for solder-
ing, contact of dissimilar metals, chemical fumes or
moisture. Also, the fingers should never touch the
metal parts of the test probes since body resistance
can cause erroneous readings - particularly on the high
ohmmeter ranges.
Care
Although this instrument is portable and rugged, it
should be treated with care. Do not drop it or handle
it roughly.
Avoid placing it on a bench where machine tools are
used or severe vibration is encountered.
When possible, keep it in a place of moderate tem-
perature. Avoid subjecting it to extreme temperatures
and severe temperature changes.
If the tester has not been used for a long period of
time, rotate the switch in both directions several times
to wipe the switch contacts for good contact.
