Model SHKE435HP and SHKE436HP shakers manage operating
time in two ways:
Hold - When time is set to Hold, the value shown in the Actual portion
of the display represents total operating time and may be reset at the
operator's convenience. The shaker will continue to count upwards even
if the console lid has been repeatedly opened and closed, or turned off
and on with the power switch. The time will, however, reset to 00:00
when the STOP button is pressed and the unit then restarted by press-
ing the START button.
Countdown - When the Hold setpoint is changed to Countdown enter-
ing a time value in hours and minutes, the platform will operate for that
period and automatically stop. The display will show the total time in
the Setpoint segment and the operating time remaining in the Actual
part of the display, as the microprocessor counts down to zero.
1. Press the button beneath the time setpoint. Hold will begin to flash.
