To ensure the connection to protective earth any
extension cord used must also have a protective earth
conductor.
Only use a mains power cord with a current rating as
specified by the calibrator and which is approved for the
voltage and plug configuration in your area.
Before switching on the calibrator make sure that it is
set to the voltage of the mains electricity supply.
Always position the calibrator to enable easy and quick
disconnection of the power source (mains inlet socket).
The calibrator must be kept free within an area of 20
cm on all sides and 1 metre above the calibrator due to
fire hazard.
Never use heat transfer fluids such as silicone, oil,
paste, etc. in the dry-block calibrators. These fluids may
penetrate the calibrator and cause electrical hazard,
damage or create poisonous fumes.
The calibrator must be switched off before any attempt
to service the instrument is made. There are no user
serviceable parts inside the calibrator.
When cleaning the well or the insertion tube,
REMEMBER to wear goggles when using compressed
air in the dry-block calibrator and cleaning oil in the
liquid bath calibrator.
Use protection shield when calibrating at high
temperatures (RTC-700)
The RTC-159 contains R-1270 and R-704 under
pressure. The calibrator must under no
circumstances be stored at ambient temperatures
above 50°C ( 122°F) or operated at ambient
temperatures above 40C (104F). Doing so may cause
a hazard.
About the front panel:
For B and C versions only, the sockets on the input
module must NEVER be connected to voltages
exceeding 30V with reference to ground.
