Safety Information
General Safety Information is located in the printed Safety Information document that ships with the
Product. It can also be found online at www.Flukecal.com. More specific safety information is listed
where applicable in this manual.
A Warning identifies conditions and procedures that are dangerous to the user. A Caution identifies
conditions and procedures that can cause damage to the Product or the equipment under test.
Follow these guidelines closely to make sure that the safety mechanisms in this Product operate
properly. This Product must be plugged into an AC-only outlet according to the
Environmental
Conditions. The power cord of the Product has a three-pronged grounding plug for your
protection against electrical shock. Plug the power cord directly into a properly grounded three-prong
receptacle. The receptacle must be installed in accordance with local codes and ordinances. Consult a
qualified electrician.
To prevent damage to the Product:
•
Always replace the fuse with one of the same rating, voltage, and type.
•
Always replace the power cord with an approved cord of the correct rating and type.
•
Protect the target against dirt and damage - scrapes and scratches. A well-kept target
surface, free from dirt and damage, produces better measurements. Use the target
cover whenever the Product is not in use to protect the target. Always use the target
cover when transporting the Product, but remember to never transport the Product
when the target temperature is >50 ° C.
•
Do not touch the target. Oils and salts from the skin will permanently damage the
target surface at high temperatures.
•
Do not use fluids to clean the target surface.
•
Do not use shop air to clean the target surface. Oil and contaminants in the shop air
could contaminate the surface.
•
Do not use canned, compressed air (used to clean a computer) to clean the target
surface. Chemicals in the air could contaminate the target surface.
•
When ice forms on the target, change the instrument set-point >50 °C to melt the
excess ice. DO NOT wipe the front plate (target). Change the set-point to 100 °C or
higher to evaporate the excess water.
•
Do not force cool the surface. The surface should not be cooled by any method other
than natural convection. Forced air can often have oil or water in it. Even water can
leave mineral deposits on the surface. Trying to cool the surface too quickly can also
cause thermal shock to the emissive surface.
•
Do not use liquid nitrogen (LN2) to quick cool the target.
•
Do not plug the Product into 230 V if the fuse holder reads 115 V. This action will
cause the fuses to blow and may damage the Product.
•
Component lifetime can be shortened by continuous high temperature operation.
