TIP
■ To avoid accidents, such as an electrical shock, which may lead to injury or loss of life to the
operator, or damage to the equipment, be sure to observe the following precautions.
_ A
WARNING_
• Do not use the instrument to measure where there is the risk of electrical shock Also, when using the 2-
channel model, always keep the probe-to-probe potential below 1 V.
• When handling a needle-type probe, be careful not to point the tip in the direction of any person as doing so
may result in an injury
• After measuring anything with a high temperature, do not touch the metal part of the measuring probe as this
may result in a burn.
_A
CAUTION _
When the instrument is stored for a long period of time, be sure to remove the batteries. Not doing so may
result in a failure or malfunctioning of the instrument due to a leakage in battery liquid
• Do not use deteriorated or damaged probes, as doing so will effect the precision of measurements.
• Before you detach the probe from the instrument, always remove the probe from the object being measured.
• When using a needle-type probe, do not insert the metal part of the measuring probe more than half its length
into the object to be measured, as doing so may result in a burn or damage to the probe due to the handle of
the probe heating up.
Keep the handle of the probe and the cable that connects the probe to the instrument within a temperature
range of -20°C to 50°C, as they are less resistant to heat than the metal part of the measuring probe.
