Operation<br />
2.1 General<br />
The <strong>Series</strong> <strong>8500A</strong> <strong>Peak</strong> <strong>Power</strong> <strong>Meter</strong>s are very simple to operate. You only need to follow the instructions<br />
given in the prompts and menus shown in the display window to set up the parameters for making a<br />
measurement. Eleven levels of operational menus are available. Each can be accessed with the MENU<br />
key. The type of measurement (<strong>Peak</strong> or CW) being made will also be shown in the lower right corner of<br />
the display to identify the mode in use.<br />
Along with the menus and prompts in the display, the power meters produce audible clicks and beeps to<br />
indicate the occurrence (or non-occurrence) of certain events during setup and testing. The tones are<br />
defined as follows:<br />
Click:<br />
When a key is pressed and a click is heard, this means that the key is active and its<br />
function will be included in the parameters being entered. If no click is heard, the<br />
key is not active and not performing any function at that time.<br />
Beep:<br />
A single beep indicates that the calibration, zeroing, or self-test functions have<br />
successfully completed when they are performed. A double beep means that the<br />
function failed to complete. The discussion of these functions later in this chapter<br />
will detail what problems might cause the function to fail.<br />
There is a volume control on the rear panel of the instrument. It adjusts the audio tones to a comfortable<br />
level, or the audio can be turned off if desired.<br />
2.2 Installation<br />
☛ NOTE: In the remainder of this chapter except where specified as the Model 8501A or<br />
8502A, the instrument may be referred to as the PPM (<strong>Peak</strong> <strong>Power</strong> <strong>Meter</strong>).<br />
The unit is set at the factory for operation at the normal supply voltage for the country in which it is<br />
sold. The input frequency must be 50, 60, or 400 Hz ±5%. The combination of the module and<br />
transformer design allows instrument operation of 100/120 volts with a 2.0 A Slo-Blo fuse, or 220/240<br />
volts with a 1.0 A Slo-Blo fuse.<br />
WARNING<br />
Before applying ac power to the instrument, be sure that the instrument is set for<br />
the correct line voltage and that the fuses are of the correct rating.<br />
Figure 2-4 illustrates the rear panel. Before operating the instrument, make sure the input voltage is<br />
correctly set and that the fuses are compatible with the applied line voltage.<br />
