GR-100 User's Manual Revision 1.2 4.0 Monitor 100U PC software
• LCD – Fills the GR-100 display with test text and allows you to change the contrast of
the LCD display with the arrows buttons. You can see the results on the
display. TEMP displays the temperature to which the contrast is calculated.
• Backlite – Enables or disables the backlight of the LCD display for test purposes. It has no
effect on the equipment settings after exiting the LCD test screen.
• Status – Displays the following info about the processor:
• the total working time
• number of loading defaults
• number of LOW count situations
• number of HIGH count situations
• number of high current situations
• serial number of the processor board
• RAM 2 kB – Tests the integrity of the RAM memory with the capacity of 2 kB. This test lasts
about 7 seconds.
• EEPROM 8
kB – Tests the integrity of the EEPROM memory with the capacity of 8 kB. This test
lasts about 8 seconds and deletes all ALARM/DIAGNOSTIC/DOSE records in the
memory.
• Spectrum – Allows remote access:
1. Set the ADC GAIN for the gamma detector (1, 2 or 4 next to G-ADC Gain
button). This will activate the LLD Spectrum or MCA Spectrum buttons.
2. Click the Gamma/Neutron button to select the status of the Gamma
detector or the Neutron detector
3. Set the time of measurement (1 to 60 seconds for LLD or any time for
MCA) in the field Time [sec.]).
The first method (LLD) is provided by moving the discrimination level. It takes
time but in some cases it can be very useful since the measurement is provided
the same way as standard measurement. Pressing the LLD Spectrum button
activates this function. The total measurement time is 40 times longer because
each channel must be measured separately.
The measured data is displayed on-line in the upper right field of the PC
screen. When the gamma detector is used the field color turns yellow. With
the neutron detector it turns blue.

Utilities
– Lets you measure the LLD Spectrum for longer than 60 seconds. The
procedures are started from the GR-100 G-Spectrum or Maintenance Mode,
which lets the GR-100 operate without communication to the computer while
the measured spectra are stored in the GR-100’s memory. After finishing the
measurement the GR-100 goes to Monitor Mode. The latest results can be
transferred into the PC after connecting via serial cable and starting the
Monitor GR100 software.
