Usage Notes
CAUTION
• To avoid damage to the instrument, protect it from physical shock when
transporting and handling it. Be especially careful to avoid physical shock due to
dropping it.
• Do not place foreign objects between jaws or insert foreign objects into the gaps of
the sensor head. Doing so may worsen the performances of the sensor or interfere
with clamping action.
• Poor performance or damage from battery leakage could result. Observe the
cautions listed below.
• Do no mix old and new batteries, or different types of batteries.
• Be careful to observe the battery polarity during installation.
• Do not use batteries after their recommended expiry date.
• Do not leave depleted batteries inside the instrument.
• Replace batteries only with the specied type.
• Keep the jaw closed when not in use, to avoid accumulating dust or dirt on the
facing core surfaces, which could interfere with clamp performance.
• The cord is hardened in freezing temperature. Do not bend or pull it to avoid
tearing its shield or cutting cord.
IMPORTANT
Inverter secondary-side waveforms and waveforms that include a large noise component may not be
measured accurately.
