Caution - Iwatsu SS-281A-H Instruction Manual

Read the following safety information. (continued)
 Hold the plug when removing the AC adaptor from the outlet.
Pulling on the AC adaptor cable will damage the cable. This may be a cause
of an electric shock, fire, or failure.
 Do not expose to rapidly-changing temperature, mechanical
stress, or impact.
The main unit, Coil Sensor, BNC cable and AC adaptor will be damaged if
exposed to these. This will be a cause of a failure.
 Do not use or store this instrument in a location with direct
sunlight, high temperature, high humidity, or dew condensation.
SS-280A series and SS-280A-H series are different in operating
temperature range of the Rogowski Coil Sensor.
Operation or storage outside the specifications could result in deformation,
deteriorated insulation, or a failure due to heat. The ranges of operating and
storage temperature and humidity are as follows:
• Operating temperature: Main Unit 0 to +40C, no dew condensation
• Operating humidity: below the moisture amount of 80%RH
• Operating altitude: 2000 m or less (at +25C or less)
• Storage temperature: −10C to +60C, no dew condensation
• Storage humidity: below the moisture amount of 80%RH
 Do not place this instrument in a location with excessive
humidity or dust.
If not, an electric shock, fire, or failure may occur.
 Do not put this instrument in a place exposed to lamp soot or
steam generated by counters, humidifiers, etc.
If not, an electric shock, fire, or failure may occur.
 Avoid pulling or bending the Rogowski Coil Sensor part with
excessive force as much as possible. The Rogowski Coil has a coil
structure consisting of an extra-fine wire rod wound tight.
Pulling or bending the Rogowski Coil Sensor part with excessive force may
degrade the specifications of the sensor part due to the change of the coil
structure.
 When adjusting the DC offset voltage (zero point), use the
included accessory Adjustment Screwdriver, align the tip of the
screwdriver with the adjustment slot, and turn it without applying
excessive pressure. The required rotation torque is less than
20 mN･m.
If using a screwdriver other than the accessories or applying excessive
pressure to ZERO ADJ of the main unit while you don't align the included
accessory Adjustment Screwdriver with the adjustment slot, you may damage
the main unit or the tip of the screwdriver.

CAUTION

Sensor SS-280A : -40C to +125C, no dew condensation
SS-280A-H: -40C to +150C, no dew condensation
