5.6.5.15.1 Auto reset
When programming High peak, Low peak, Time average, Gated timer and Totalize points, the system
allows an Auto reset function. If Auto reset is disabled, resettable points may only be reset manually.
If Auto reset is set up, the point being programmed will reset at programmed intervals, from once a
minute to once a month.
NOTE: High peak, Low peak and Moving average points reset to the current value of the Basepoint.
Totalize points reset to zero.
To set the Auto reset function:
From the Reset control menu use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Auto reset and press
the ENTER button. The Auto reset Setup menu will be displayed with the following options: Auto off,
Daily, Weekly, or Monthly.
a. Auto off
If the Auto reset is set to off, automatic reset of the programmed point will be disabled. Use the
UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Auto off and press the ENTER button. Press the EXIT
button to return to the Reset control menu.
b. Daily
When programming the Auto reset to Daily, the system will prompt for the start time and interval
for which that point will reset. The programmable start time is not necessarily the time at which
the first reset will occur. However, a reset will always occur at the start time every day. The actual
first reset depends upon the current time and the programmed interval. The Recorder calculates
the first reset by repeatedly adding the interval to the start time until the current time is met or
exceeded. See the example below:
