Pay attention to the following precautions when using
Rapport337.
Do not use the unit in damp humidity or leaking gas environments.
Do not touch it with wet hands.
Be mindful not to shock or shake the unit while in use to avoid
damage.
Avoid the places of strong magnetism or electric wave, which
would cause incorrect measuring.
Be careful not to expose the ports or joints to dirt or liquid.
Make sure to use specified replacement fuses described in the
3rd chapter.
Do not disassemble the Rapport 337.
Do not use the meter function, when the Rapport337 or the lead
set look damaged.
Do not measure resistance when the power is applied to a circuit.
When using the meter function, do not forget to turn on the power
of Rapport337 and set up the proper measurement mode before
connecting to a circuit to be measured.
Turn off the power to the circuit to be measured and discharge all
high voltage capacitance before starting resistance or continuity
tests to avoid damage to the Rapport 337.
Put the finger behind the protecting pad when using a probe.
