This equipment is intended for use in electrostatic processes that are free from water, oil, solvent
and other conductive contaminants. Exposure to such contaminants will cause failure of the
electrical insulation system in the product
This equipment must have proper grounding for accurate measurement.
This equipment is likely to be damaged if dropped. In such an event, it should be carefully
examined and any necessary repairs be made by an authorized technician.
This is an electronic instrument and contains sensor that is sensitive to mechanical
vibrations and shock. As it also contains a microcomputer chip and electronic circuitry, it should
not be used in an environment where there is a lot of electromagnetic noise.
Suspend measurement when the voltage reading is outside the measuring range. If the range is
exceeded, there is a possibility of damaging the sensor.
It is possible to use this product in ionized air. However, normally specified accuracy of 5% cannot
be guaranteed in this case
Do not exert any pressure on the LCD display from the top.
In rare cases cleaning the PFM-711B, case and display with a slightly dampened cloth may be
required. Should this be required, use a very weak solution on of liquid soap and water. The cloth
should be barely damp. DO NOT allow the instrument to become wet with the cleaning solution.
The instrument has been calibrated for a measuring distance of 1” (25 ±0.5 mm). This
calibration is not valid outside this distance. Do not tamper with the sensor location and the
guiding LEDs for that could alter the measuring distance
DO NOT allow cleaning solution to enter the unit through apparatus openings. Should the unit
become damaged with cleaning solutions, the warranty is voided.
Do not expose this apparatus to dripping or splashing.
Do not dispose of batteries in a fire.
Do not short-circuit, disassemble, or overheat the batteries.
