local oscillator or test signal, it is desirable to have a steady and constant-frequency signal, and the
VFO mode provides just this.
d) SETUP--
Pressing the SETUP pushbutton presents a menu of functions to allow setting of configurable
options in the instrument. Rotate the dial to display the desired function, then press the dial to select
that function.
• Start Frequency
– This function allows the user to set a custom Start Frequency for the scan
operation. This custom-set parameter is used when the Custom Band item is selected in the
BAND menu.
•
End Frequency
– This function allows the user to set a custom End Frequency for the scan
operation. This custom-set parameter is used when the Custom Band item is selected in the
BAND menu.
•
Set Scan Step Size
– This function allows the user to select the step size to be used for the Scan
operation. Available step sizes are 100 kHz, 10 kHz, 1 kHz (default), and 100 Hz. This custom-set
parameter is used when the Custom Band item is selected in the BAND menu.
•
Enable Tones – This function provides an audible tone whose pitch corresponds to the SWR
being measured when in Impedance mode. This feature is useful in eyes-free conditions or by the
visually-impaired.
•
Disable Tones – This function disables the audible tone. (Default setting.)
•
Turn Lite On
– This function turns on the display backlight. After a user-settable amount of
instrument inactivity, the backlight will turn off. When the user touches any of the controls again,
the display backlight will again turn on.
•
Turn Lite Off – This function turns off the display backlight. (Default setting.)
•
Lite Off Time
– This function prompts the user to enter the number of minutes of inactivity
before the display backlight is automatically turned off. (Default value is 10 minutes)
•
Power Off Time – This function prompts the user to enter the number of minutes of inactivity
before the entire instrument is automatically turned off. When the user touches any of the controls
again, the timeout counter is reset to this user-entered value. (Default value is 10 minutes.)
• Battery Voltage
– Select this function to display the approximate voltage of the battery.
•
Default Settings – This function restore the default settings of all data stored in nonvolatile
EEPROM memory.
• View Settings
– This function sequences through a display of all settings stored in nonvolatile
EEPROM memory when the dial is turned.
•
Debug Mode – Enabling the Debug mode sends raw measurment data out the serial port which,
when the instrument is connected to the the serial port of a PC, can provide diagnostic information
about the ZM-30 operation in the field. (Default setting is OFF.)
•
Calibrate – Entering this function instructs the operator to follows a sequence of steps that result
in new calibration data being stored on the unit. This is a useful function to be performed in the
field when a new software program is loaded, necessitating a recalibration. (For additional detail
on Instrument Calibration, please refer to Appendix E.)
•
Update Software – This function is used when upgrading the ZM-30 software in the field.
Whenever newer or improved capability software is available, the user may download the binary
file from the PalStar website to his local PC. (For additional detail on upgrading ZM-30 software
programs in the field, see Appendix D.)
