Platinous User’s Manual 13
Precautions in Usage
2.4 Other Precautions
Observe the following precautions when using the chamber.
Ground the equipment WITHOUT FAIL.
For details on grounding, See “Power Supply Work” on page 39.
Use only the specimen power supply control terminals to apply
voltage to specimens.
Specimens generate heat as they are charged. The specimen power supply control terminals are
interlocked with the chamber control circuit, so power to specimens is turned OFF when the
chamber is not running. Using other means to charge specimens leaves the specimens charged in
the event of chamber trouble. This can drive up temperature inside the chamber, which can
damage specimens and in worse cases result in fire. See “How to Power Specimens” on page 55.
FIGURE 2.5. TEMPERATURE AND SPECIMEN POWER SUPPLY CONTROL TERMINALS
HOT AIR BLAST WHEN OPEN! Use caution when opening the door
during and shortly after operation at high temperature or high
humidity.
Hot (wet) air is blown from inside the chamber when opened.
HOT ON THE INSIDE! During and shortly after operation above
55°C, the chamber is HOT on the inside (including specimens, shelves, door gasket, and
test area walls).
Direct contact may result in burns. Wear heat resistant gloves.
COLD ON THE INSIDE! During and shortly after operation below
0°C, the chamber is COLD on the inside (including specimens,
shelves, door gasket, and test area walls).
Direct contact may result in cold burns. Wear cold resistant gloves.
DO NOT introduce electrically conductive specimens which might
easily be thrown about by air currents inside the chamber.
Specimens of this sort can cause leaks in the heater if they infiltrate the air conditioner.
