It is a 2-speed fan and at lower set point temperatures the fan speed
will increase (shown by indicator 02 on the controller).
Allow at least 150 mm of space all around the unit and DO NOT obstruct
any of the ventilation holes.
STAND
The stand can be folded flat against the under side of the unit when not
in use or, if the unit is to be operated in a horizontal position, it can be
swung down and forward until it hits the stops so that the unit can be
used in an inclined position. The stand was not designed to be a carrying
handle and should NOT be forced past the stops for this purpose.
DRY-WELL
The aluminium dry-well is located on the front panel. The dry-well is
designed to accept two inserts: Ø4.8 and 6.4 mm as standard. Other
inserts are available to suit standard probe diameters. Use the nearest,
larger size insert to the probe diameter being checked. The inserts are
a close fit in the dry-well to give good thermal conduction. Keep the
inserts clean and avoid damage by storing carefully. The inserts MUST
be regularly removed and cleaned to ensure they do not seize in the
dry-well. DO NOT introduce any liquids or substance into the dry-well
or inserts as this may result in the inserts lodging in the dry-well.
TEMPERATURE CONTROLLER
In normal operating mode the numeric LED display shows the actual
well temperature. A Control Output Indicator light (O1) is located in
the top left corner of the display. This indicates when the unit is in heat
mode or when the unit is controlling within the proportional control band.
To show the set point temperature in the display, press and release
either the up or down arrow button (
˄˅
). Press and hold either the up
or down arrow button (
˄˅
) to change the set-point value.
A shift can be entered into the controller by pressing the scroll (left-hand)
button. Press and hold either the up or down arrow button (
˄˅
) to
change the shift value. A factory set value will be entered at the time of
certification. The shift value should only be adjusted if the unit is being
monitored by an ETI Reference Thermometer or similar.
All other functions of the controller have been factory set and locked to
maintain accuracy and repeatability.
