5.1.2 VIEW PEAK VALUE
The maximum Process Variable value measured since switch-on or last reset of
Peak/Valley (See 5.1.4), is continuously calculated within the instrument. The current
value may be inspected by pressing the SHIFT key whilst in Display PV mode. The
display will briefly show PEAc before revealing the actual peak value. This value will
remain displayed until 1s after the key is released. It will then return to the Process
variable display.
5.1.3 VIEW VALLEY DISPLAY
This operates in exactly the same way as the View Peak display except that the INC
key is used and the minimum Process Variable value displayed.
5.1.4 RESET PEAK/VALLEY & CLEAR LATCHED
ALARMS
Pressing the CYCLE and INC keys simultaneously performs two independent
functions. It sets the Peak and Valley values to the current Process Variable value
and it also clears any latched alarms.
