• Always wear safety glasses when working in electrical circuitry.
• Do not work alone on high voltage circuits. Make certain that someone capable of rendering aid
is nearby and watchful.
• Do not handle the Instrument, its test leads, or the circuitry while high voltage is being applied.
• Do not connect any terminal of this Instrument to a circuit point at which a voltage exceeding 600
volts AC or 600 volts DC may exist with respect to earth ground.
• Turn off power and discharge any capacitors in the circuit to be measured before connecting to
or disconnecting leads from that circuit.
• Prior to use, check the Instrument, the accessories (if any), and the test leads for missing,
damaged, deteriorated or otherwise faulty insulating parts. Do not use, or permit the use of,
equipment with faulty insulation until it has been properly repaired.
• Avoid making measurements under humid, damp or other environmental conditions that could
reduce the dielectric strength of the test leads or Instrument and increase the possibility of
electrical shock.
• Do not change Instrument switch settings or test lead connections while the circuit is energized.
A mistake could result in damage to the Instrument and possible personal injury.
• Locate all voltage sources and accessible current paths before making connections to circuitry.
High voltage may appear unexpectedly or in unexpected locations in faulty equipment.
An open bleeder resistor, for example, may result in a capacitor retaining a dangerous charge.
• Make certain that the equipment being worked upon is properly grounded and fuses are of a
proper type and rating.
• Check and double check switch positions and jack connections before applying power to the
Instrument.
• Always remain alert for low voltage circuits which may be floating at high voltage with respect
to earth ground and for composite voltage (AC + DC). Such composite voltage must not exceed
the Instrument’s rated maximum circuit-to-ground voltage.
• Do not make electrical measurements where the air may contain explosive concentrations of
gas or dust.
• When in doubt as to the range to be used, first select the highest range available. After an
initial reading, the range can be changed to one that is more appropriate to the value indicated.
• This General Purpose VOM is NOT to be used to make electrical measurements on blasting
circuits or blasting caps.
