Remote Alarm System

2-16 Model SHKE8000 Series Shakers
Calibration Procedure
1. Set up a typical operating load in the shaker. Place a measuring device
(of known accuracy and calibrated to a national standard) near the
main control probe, clipped to the right side chamber wall just behind
the baffle for the intake grille.
2. Set Temp to 37.0°C and Speed to 75 RPM.
3. Start a cycle and allow the shaker to stabilize for approximately one
hour.
4. Adjust the calibration as described above so that the Actual display
reads 37.0°C, ±0.3°C.
Any of the alarm states described previously can alert a remote alarm
monitoring system through an internal SPDT relay connected to an RJ-11
connector on the left front of the shaker, behind the kick panel. Refer to
Section 1 of this manual for set-up. For the convenience of the laboratory,
these remote alarms can be individually turned on or off. Any or all of the
remote alarms that are set to On will activate the internal relay.
If no buttons are pressed, the display will automatically return to the
Operating Screen after about fifteen seconds, saving the selection to
memory.
Note The Remote Overtemp Shutdown and Check Fuse alarms cannot be
deactivated.
