NOTE
indicates precautions necessary to avoid
potential equipment failure.
This equipment must be installed and maintained as
outlined in this manual. This equipment is not
constructed for classified (hazardous) environments. It
cannot be used where it will be exposed to ignitable or
corrosive materials.
The
19430
is intended for use in areas that are free of
water, oil, solvents and other conductive
contaminants. Exposure to such contaminants will
cause failure of the electrical insulation system in the
product. Formulation of dew on the fieldmeter must be
avoided.
Do not operate near corrosive fumes of acid/alkali or
corrosive gases such as chlorine. The
19430
must be
properly grounded to function accurately.
The
19430
contains a microcomputer chip. It should not
be used in an environment with excessive
electromagnetic noise. The internal parts of the
19430
should never come in contact with foreign
substances.
The
19430
has been calibrated for a measuring
distance of 1”± 1/64" (25mm ±0.5mm).
Important Notes and Cautions
1. Store and use the fieldmeter in a clean and dry
environment. Foreign substances should never enter
or touch the internal parts.
2. Vibration and impact may damage and/or affect the
sensitivity of measurement of the instrument.
3. Do not attempt to take apart the fieldmeter.
4. The measuring distance between the fieldmeter and
a test object should be 1” ± 1/64” (25mm ± 1mm).
The calibration was carried out at this distance. The
specified accuracy is valid for this distance.
