■ Since mishandling the instrument can result in an accident that may lead to injury or
death of the operator, such as an electric shock, be sure to observe the following instructions.
WARNING
● Measurement
• Always maintain the instrument within the limits for allowable current, voltage and power, during operation.
If there is more than one limit for any of these parameters, the lowest limit takes precedence.
• Only operate the instrument on an input-to-ground supply voltage of no greater than 250 V
(except for Model 279303).
• When an input-to-ground supply voltage of greater than 250 V needs to be applied to Model 279303,
exercise extra care when handling the instrument.
• The terminals and internal circuitry may become electrified to high voltages and extremely hot depending on
the instrument’s condition of use. Do not touch these parts.
● Grounding
• To avoid electric shock, be sure to apply protective grounding to the grounding terminal.
● Protective Measures
• If a crack appears in the instrument after it has been accidentally dropped or bumped,
the safety-purpose insulation may be damaged.
By all means do not use the instrument, but ask the manufacturer for repair.
● Operating Environment
• Do not operate the instrument in a flammable or explosive gas atmosphere.
• Do not operate the instrument if there is any condensation on it.
● Do Not Remove the Casing or Disassemble
• Only Yokogawa service personnel are authorized to remove the casing or disassemble or
modify the instrument.
Do not attempt to repair the instrument yourself, as doing so is extremely dangerous.
(If you are rack-mounting the instrument, use it correctly according to the handling procedure.)
