1.4FRONT PANEL CONTROLS

The front panel consists of four areas, the display screen, the key pad, a full keyboard and a touch pad. The display screen is the area under the glass in the center of the front panel. The key pad is to the right of the display screen and contains membrane keys. Note the keyboard and touch pad fold down 90 degrees from under the display screen and key pad.

Throughout the preventive maintenance procedures, whenever a key is to be pressed, the appropriate key name is surrounded by square brackets as in the following example:

Press the [CONFIRM] key and the screen will change.

In this example, the [CONFIRM] key on the touch pad should be pressed.

Touch Pad Operation

The touch pad is designed to allow the user to move an arrow around on the display screen. To select a button during a procedure, use the touch pad to move the arrow over the button on the screen. Tap the touch pad to select the on screen button.

Depending on the type of button, the screen will change. Data boxes are also displayed on the display screen. The following describes the type of buttons and data boxes that will be encountered during the preventive maintenance process.

Data Button

A yellow data button is used to enter a measured volume or value. When the yellow area of the data button is selected, it will change to a darker yellow. The data can be changed using the [▲] and [▼] keys or the value can be entered using the number keys. Once the data is entered, press the [CONFIRM] key and the data button changes back to light yellow. The [Escape] key can be pressed when the data button is dark yellow to abort the data entry and return it to light yellow. The entered data does not get stored until the [CONFIRM] key is pressed.

Some data buttons will change the screen and the data entry will be performed on the new screen.

A gray data button means the button is not active and selecting it will have no effect.

1.5MEASURING FLUID VOLUMES

Several of the following procedures require measuring fluid volumes using graduated cylinders and laboratory burets. When making these measurements do the following:

•Make certain the container is clean and dry before collecting the fluid to be measured. Two drops of fluid are approximately 0.1ml, which is enough to affect the accuracy of critical measurements.

•Ensure that no items such as thermometers or tubing are allowed to come in contact with the fluid in the graduate. Such items will change the calibration of the graduate and affect the accuracy of measurements. Both the total volume indicated and the amount of fluid indicated by each increment on the graduated scale will be incorrect. For example, if a graduate is calibrated in 1ml increments, a piece of tubing in contact with the fluid will cause each increment to be less than 1ml, depending upon the total volume of the tubing that penetrates into the fluid.

•Surface tension causes the fluid to curve into a meniscus (See Figure 1). Measure the volume at the bottom of the meniscus curve as shown.
