The i4 Semen Evaluation Microscope comes equipped with a built-in heated stage. The dual heating elements and
thermostat are mounted inside the stage, and the PID temperature controller unit is mounted into the rear panel of the
microscope. The red power switch is on the front right panel of the microscope, which will illuminate when power to the
heated stage is turned on. Once turned on, the PID temperature controller will show the actual temperature of the
stage, and the temperature will gradually increase until it reaches the preset temperature. The stage should reach the
correct temperature within 5-10 minutes, depending on ambient temperature. The heated stage may possibly
over-shoot the correct temperature slightly, but will settle onto the correct temperature within a few minutes. It is best to
turn on your stage 15 minutes before any procedure.
All programming functions of the PID controller have been preset by LW Scientific, and the temperature has been preset
to 98.6 degrees F. There are many complicated programming functions built into the PID controller, which should not be
altered by the customer. The only two functions that may need to be altered by the customer are “Set Temperature”
and “Change from Fahrenheit to Celsius” as described below. If there are any other programming functions that need
to be altered, or questions about the operation of the heated stage, please call the LW Scientific technical support
department at 800-726-7345.
