Handling the instrument
To avoid electric shock, do not remove the instrument's case. The internal com-
ponents of the instrument carry high voltages and may become very hot during
operation.
• If the instrument exhibits abnormal operation or display during use, review the infor-
mation in Troubleshooting section "11.2 Trouble Shooting" (p. 219) and Error Indi-
cations section "11.3 Error Indication" (p. 222) before contacting your authorized
Hioki distributor or reseller.
• To avoid damage to the instrument, protect it from physical shock when transporting
and handling. Be especially careful to avoid physical shock from dropping.
• To move the instrument, first disconnect all cables, remove any CF card and USB
memory, and carry it by the handle.
• Do not apply heavy downward pressure with the stand extended. The stand could
be damaged.
See "Using the Handle as a Stand" (p. 15)
• Use a common ground for both the instrument and any devices to be connected.
Using different ground circuits will result in a potential difference between the instru-
ment's ground and the computer's ground. If the communications cable is connected
while such a potential difference exists, it may result in equipment malfunction or
failure.
• Before connecting or disconnecting the communications cable, always turn off the
instrument and any devices to be connected. Failure to do so could result in equip-
ment malfunction or damage.
• After connecting the communications cable, tighten the screws on the connector
securely. Failure to secure the connector could result in equipment malfunction or
damage.
This instrument may cause interference if used in residential areas. Such use must be
avoided unless the user takes special measures to reduce electromagnetic emissions
to prevent interference to the reception of radio and television broadcasts.
