Checkline FGV-XY - Manual (Page 16)

NOTE: The values entered for the HI and LO settings are displayed in the
measurement units last used in Standard Mode.
NOTE: The absolute value of the HI limit can never be lower than the
absolute value of the LO limit.
7.3 Setting the LO Limit
1. Press UNIT to select the HI Setting. The digits will
start flashing.
2. Press PEAK. This saves the HI limit and displays
the LO limit.
3. Press UNIT again to change the polarity.
4. Choose the digit to change by pressing ZERO.
5. Press UNIT to increase the selected digit to the desired value.
6. Repeat steps 3 and 4 until the desired value and polarity are correct
7. Press MEM if you are finished with the Comparator and Memory
settings.
NOTE: The absolute value of the LO limit can never be higher than the
absolute value of the HI limit.
7.4 Comparator Display
The following symbols are shown when the Comparator function is active:
NOTE: In order for the Comparator function to display, the Comparator
output option must be set in function f06. See section 4,.6 regarding this
setting.
7.5 Comparator Output
The Comparator function also allows control of an alarm or automated
process through its data output port. When the measured value is greater
than the HI limit, the corresponding photo-couple is triggered. When the
measured value is lower than the LO limit, the corresponding photo-couple
is triggered.
NOTE: In order for the Comparator function to display, the Comparator
output option must be set in function f06. See section 4.6 regarding this
setting.
NOTE: For connection and circuit information pertaining to the
Comparator output see section 12.6.

WARNING
The Comparator function’s limits can be set outside of the FGV-XY’s working
range. This may cause unpredictable results, and is not recommended

9.1 Continuous Mode Memory
Accessing Memory Data
1. Turn the POWER off.
2. Press MEM and hold, then press and release POWER. Release MEM
when you see “CNT” on the display. The unit will alternate between
showing the data block number and the recorded measurement value of
that block.
3. Press MEM to review the previous data block recorded.
4. Press UNIT to cycle through the available recorded statistics. In
Continuous mode the available statistics are as follows: positive
maximum value, negative maximum value, positive minimum value,
negative minimum value, positive peak value, negative peak value,
average value, standard deviation
5. Press PEAK to output the recorded data via RS232C. See section 12.
NOTE: Pressing ZERO deletes the current data block, but only if you have
the last black selected
Statistics Data
1. When in memory mode, UNIT will cycle through the available
statistics data.
2. Each press of UNIT will switch between the following items: positive
maximum value, negative maximum value, positive minimum value,
negative minimum value, positive peak value, negative peak value,
average value, standard deviation.
3. Press MEM to exit to the recorded measurement values.
4. Press PEAK key to output the recorded memory via RS-232C.
(See section 12).
NOTE: Pressing MEM exits statistics mode and returns to memory blocks.
