WARNING
●Never make measurement on a circuit in
which the electrical potential exceeds 690V.
●Do not attempt to make measurement in the
presence of flammable gasses, as the use
of the instrument may cause sparking,
which could lead to an explosion.
●Never attempt to use the instrument if it's
surface or your hands are wet.
(Do not use in rainfall.)
●Keep your hands and fingers behind the
barriers during measurements.
●Never unlock and open the Battery case
during measurements.
●Verify proper operation on a known source
before use or taking action as a result of the
indication after use.
●Never attempt to make any measurement if
any abnormal conditions, such as a broken
case or exposed metal parts are present on
the Instrument or test probes.
●Do not make any modification to the
instrument.
●Extreme caution when Live circuit LED
flashes or lights on.
●Correct indication of LEDs is only guaran
teed within a temperature range of -10°C up
to 55°C (<85% RH).
