Preface
To use the thermometer correctly and safely, please keep the following safety measures for the operation
and storage of the thermometer.
1. Working conditions and environment
∙
The working temperature range of the thermometer is 0 to 50 °C. (No dew condensation)
∙
Do not use the thermometer in dusty places, etc.
Remove the dust after using it.
∙
Be careful not to give vibration or impact to the thermometer. Install the thermometer as far as possible
from an inductive oscillator or electric power line.
∙
The fiber optics is consisted of the single-core quartz fiber and the sheath. Two kinds of the sheath are
available.
∙
The maximum working temperature of the fiber optic assembly is 150ºC.
2. Storage
∙
Do not store the thermometer in hot and humid places.
∙
Two types of the fiber optics are available, one is the single-core quarts optical fiber covered by a
heat-resistant sheath with glass wool over braided, and the other is the single-core quarts optical fiber
covered by a heat-resistant material with the glass wool over braided and, and further covered by
flexible metal tube sheath. For the storage of the fiber optics, keep it with the bending radius larger than
the allowable value (R: about 100mm).
∙
Make sure to connects the optical connectors of the fiber optics to the optical connectors of the
thermometer and the lens assembly with the proper key slit position. Don’t crack the fiber optics sheath
or make it dirty. (Ref. [4.3 Cautions on installation/maintenance of fiber optics])
∙
For failures of the thermometer, don’t overhaul it by yourself, and contact your sales agent of CHINO
Corporation.

Warning
The thermometer has been calibrated with a fiber optic assembly consisted of a fiber optics and a lens
assembly. Connect the correct fiber optic assembly to the thermometer.
(Ref. [3.1.1 Thermometer view] and [3.3 Fiber optics])
The fiber optics has a direction of the thermometer side and the lens assembly side, and the
thermometer has been calibrated with the correct directional fiber optics. If you connect the fiber optics
with the opposite direction to the thermometer, you will have an indication error.
