5.5: Accessing Max/Min Values


Max/min values represent the highest and lowest average demand over a user programmable time period
known as the Integration Interval. The readings are calculated using a rolling average technique. Each
second, a new reading is used to calculate the max/min; the last reading of the interval is dropped off.
The highest max during an averaging period is stored until the user resets the max/min. This is similar to
amp demand meters. It is commonly referred to as Thermal Demand.

To access a max/min value while displaying a desired measurement, press MAX/MIN/LIMITS—once for
the max value; twice for the min. Examples given below are for voltage and current phases. Use the
same procedure for all other parameters.

Step 1:

a. To select the Volts category,

press VOLTS.

!

The display blanks and all

annunciators glow, confirming

selection.

Step 2:

a. Press PHASE/NEXT for the

desired phase.

Step 3:

a. Press MAX/MIN/LIMITS once

to view the maximum reading for

Volts C-N.

!

The display blanks and

momentarily indicates the max

value.


To access KW, KVAR and PF negative measurements indicating leading current, press MAX/MIN/LIMITS
five times for negative max and six times for negative min.

5.6: Resetting Values


Use the reset function if a new value is desired. It is available in two different modes.

1.UNPROTECTED MODE: Allows quick and easy resetting of max/min values.


2.PROTECTED MODE: Prevents unauthorized resetting the max/min and totaled power functions.

Note: Even if the unprotected mode is selected during programming, the KWH and negative KWH

are always in protected mode. The following examples are for the max/min.
