4.4.5.6 A-B)% Display
This display mode is only available on dual probe model monitors. In the Dual
Probe measurement mode, this display shows the percentage difference between
A and B probe measurements. The right four characters of the Parameter/Status
display indicate the percentage difference between the measurements made by the
A and B probes, the average of which is displayed in the right hand Main display.
The quantity displayed is 100*(A- B)/(A+B) or the percentage that the
measurement A is larger than the average of the two measurements. The format
of the display is +XX.X or -XX.X. A positive sign indicates that the A
measurement is larger than the B measurement. The left four characters of the
Parameter/Status display indicate the percentage difference between the
measurements made by the A and B probes, the average of which is displayed in
the left hand Main display. The same format is used.
4.4.6 Simulation Mode
The PM-700 series of monitors include a simulation function that is useful for
familiarization and demonstration of the monitor features and for trouble
shooting. In the simulation mode the frequency signal from the Probe is replaced
with a simulated frequency that reflects the change in frequency, which an ideal
crystal would produce when plated at the rate, specified by the Simulate Rate
parameter. The Simulation State is activated by the Simulation Mode parameter.
4.5 PARAMETERS
The PM-700 series of monitors incorporate a large number of parameters that
allow fine-tuning of the monitor for a particular application. All parameters are
provided with default factory set values so that the user need only be concerned
with those parameters that he desires to change. There are two different types of
parameters; they are the selection type and the value type. Selection type
parameters are parameters that are limited to a small number of possible
selections. Some have only two selections, On and Off. Value type parameters
may have any numeric value between a maximum and a maximum value.
4.5.1 Viewing and modifying
Pressing any one of the arrow keys results in the display of the last viewed
parameter. The parameters are arranged in five different menus according to their
usage. See Figure 6. Once a parameter is displayed, the left and right arrow keys
provide for horizontal movement as shown in Figure 7. The up and down keys
allow for vertical movement which corresponds to selection of selection type
parameters or for increasing or decreasing the value of value type parameters.
Note that movement between menus is only available when menus are being
displayed as indicated by the vertical lines between the menu selections. Holding
the left arrow key down will rapidly take you to the menu parameter. The up and
down keys can then be used to choose a particular menu. The rate at which value
type parameters change value increases for as long as a direction key is held
down. When the key is released, the rate of change returns to its minimum value.
