10.11 Entering Setpoint Levels (In Run Mode)
When you have completed selecting the setpoint(s) (and other features), the last press of the ‘MENU’ button stores
any changes and the meter will automatically return to the run mode (the display will momentarily display
“RESET2”). The stored values are placed into operation, and the meter proceeds with normal measurements.
Now you can view and reset all four setpoint levels.
1. Press the ‘SETPTS’ button. The meter now starts its setpoint display cycle; every 15 seconds, the display
flashes the SP number, and then displays the value of that setpoint, with a flashing left-hand digit.
2. You can restart the time-out of any of these display intervals by pressing the ‘MIN’ button (to shift the flashing
[alterable] digit position), or by pressing the ‘MAX’ button (to increment the value of that digit).
3. When you change the value of any setpoint and then decide to revert to the original value instead, just press
the ‘RESET’ button or allow the display to return to “RUN” at the end of its cycle. The meter does not store a
new value for the setpoint in either case.
4. To save a newly entered setpoint value, press the ‘SETPTS’ button again.
5. You may return to viewing the measurements by pressing the ‘RESET’ button or repeatedly pressing the
‘SETPTS’ button (or by letting the meter complete its setpoint display cycle).
11.0 PEAK AND VALLEY READINGS
The meter examines every new reading to see if it is greater than the stored PEAK or less than the stored VALLEY
readings.
If you have unlocked access to these values with “L1C.5=0” and “L1C.6=0” (part of the first lockout byte “L1 CNF”),
you can view the PEAK (“HI RDG”) by pressing the ‘MAX’ button, or the VALLEY (“LO RDG”) by pressing the ‘MIN’
button while in the run mode.
Selection of either PEAK or VALLEY causes the display to flash giving the indication that it is NOT the current
measurement value. If the meter measures a more extreme value while displaying the PEAK or VALLEY
measurement, the new value will immediately replace the old.
Unlike the setpoint display, there is no time out period. Press the ‘SETPTS’ button or ‘MENU’ button to return to
current value display WITHOUT resetting the PEAK or VALLEY memory.
Press the ‘RESET’ button to return to run mode and start a new PEAK/VALLEY measurement period.
The BCD option can be programmed to read the PEAK (but not the VALLEY) instead of the current measurement
(refer to Section 13).
Both PEAK and VALLEY readings (and/or a PEAK/VALLEY status summary character) can be transmitted by the
RS-232 or RS-422/485 digital communications (refer to Section 15).
The PEAK or VALLEY value can be transmitted via the optional analog output board (refer to Section 12).
12.0 ANALOG OUTPUT OPTION
If you received your meter with the optional analog board installed, you should not have to enter the trim data as
described in Section 12.5.
