Operation
Set the Temperature Alarm
Tracking Limit
2-14 Model SHKE8000 Series Shakers
The Temperature Tracking alarm activates whenever the operating
temperature goes above or below the setpoint temperature by a
predetermined value. This adjustable limit is set at the factory as 10° above
and below the temperature setpoint.
Note The above and below limits are always the same value.
To change this limit, open the Configuration menu as in the previous
alarm procedures, by pressing the down arrow, up arrow, and the Silence
button in that order.
When this screen opens, press the
down arrow once ....
Then press the temperature
button beneath Alarms.
From the screen at right, press the
temperature button beneath
Tracking.
The following screen appears and
the present Temperature Tracking
alarm limit setting flashes.
Change the Temperature Tracking limit by pressing the up or down arrow.
When set, press the Temperature button to save the setting and return to
the previous screen. If no buttons are pressed for about fifteen seconds, the
display returns to the Operating Screen, saving the new setting to memory.
If chamber temp rises above or falls below
the temp tracking limit, the appropriate
message displays, the warning lights flash
and the audible warning (if not turned
off ) sounds.
Pressing Silence turns off the audible alarm. However, the warning lights
continue to flash and the alarm message displays until the high/low temp
condition is corrected. The audible warning also sounds again in about 15
minutes if the over or under temp tracking condition persists. When the
fault is corrected, press Silence to clear the alarm message from the display.
