Operating Precautions
Before connecting the power cord to the instrument
DANGER
Use only the designated power cord with this instrument. Use of other power
cords may cause re.
WARNING
• Before turning the instrument on, make sure the supply voltage matches that
indicated on its power connector. Connection to an improper supply voltage
may damage the instrument and present an electrical hazard.
• To avoid electrical accidents and to maintain the safety specications of this
instrument, connect the power cord provided only to a 3-contact (two-conductor
+ ground) outlet.
CAUTION
• Do not connect the supply voltage improperly. Doing so may damage the instrument’s
internal circuitry.
• To avoid damaging the cords, unplug it by grasping the connector, not the cord.
Before connecting the measurement leads and electrode to the instrument
WARNING
• Do not use the instrument with circuits that exceed its ratings or specications.
Doing so may damage the instrument or cause it to become hot, resulting in
electric shock.
• The maximum rated voltage to earth of the input terminal is 1000 V DC for Model
SM7110 and 2000 V DC for Model SM7120. Do not apply any higher voltage
input to the input terminal.
• Use only the specied measurement lead. If using a measurement lead other
than the one specied, you cannot perform measurement safely.
• To avoid electric shock, do not exceed the lower of the ratings shown on the
instrument and test leads.
Before connecting the Humidity Sensor to the instrument
CAUTION
• The sensor used in the Humidity Sensor is a thin, precision platinum lm. Be aware
that excessive voltage pulses or static discharges can destroy the lm.
• Avoid subjecting the tip of the Humidity Sensor to physical shock, and avoid sharp
bends in the leads. These may damage the probe or break a wire.
• Note that the ambient temperature does not exceed the temperature range specied
in Refer to “Specications of Model Z2011 Humidity Sensor” (p. 144).
