1.3 VARIABLE SPEED OPERATION

The speed of the Omni GLH may be regulated by means of a variable
rotary switch located at the top of the unit. Speed settings below are
approximate, and are based on running a 35mm probe in water. Actual
speed will vary with probe size and sample processed.

1.4 EXTERNAL SPEED CONTROL

For greater precision, range (0–28,000 rpm), or remote operation
(such as for fume hood or cold room applications) the optional
external speed control is recommended. To operate the Omni GLH
with the external speed control:
1. Make certain that both the external speed control
and the Omni GLH are in the OFF position.
2. Plug the speed control into an external power source.
3. Plug the Omni GLH into the rear of the speed control unit.
4. Set the speed control knob on the Omni GLH to 6
(the maximum setting).
The Omni GLH can now be operated via the external speed control dial.
Select the optimal speed for each different combination of sample and
generator for best processing results.
The table on page 7 is a good approximation guide for operating speed.
