Figure 3. Front Panel
Process Temperature/Setpoint Temperature Display:
In the default mode, the display will show the process temperature, i.e. the
target plate temperature. When the modify key is held down, the setpoint
temperature is displayed.
Target Plate:
The 1.125" target plate is a near ideal blackbody source. The emissivity
of the plate is .95. When calibrating an IR pyrometer, hold the pyrometer
perpendicular to the target plate for optimal performance. The proper distance
between the IR pyrometer and the target plate depends on the field of view of
the pyrometer. If the pyrometer is too far away it will scan unwanted surfaces
outside of the perimeter of the target plate. Holding the pyrometer too close
could introduce undesirable heat to the IR detector of the pyrometer.
• The BB703’s target plate can be set to very high temperatures. Exercise
extreme caution when operating the unit. Keep hands and fingers away
from the target plate area. Keep flammable products such as paper,
plastics and clothing far from the BB703.
• The BB703 is a Class II instrument. It is intended to be operated in laboratory
environment only. Never operate the unit outside or around children.
• Nothing should come in contact with the target plate. Even when the unit is off.
• Never unplug the unit while it is on or during “Cool Down.”
P.I.D. Indicator:
When this light is illuminated, the unit is heating up the target plate.
