3.6 Scaling Settings (as needed)

Integrated pulse values can be converted for display as physical units of the measure-
ment parameter (such as Wh or VA).
Pulse output devices determine the amplitude per pulse in physical units, or the number
of pulses per fundamental unit (for example, per kWh, liter or m

).

Integration Measurement Scaling Setting
With Dec setting
1 Select the desired numerical notation.
2 Enter the [Unit] name on the comment entry
screen.Enter the [Unit] name on the comment
entry screen. (Up to 7 characters)
See: About Comments (p. 71)
3 Specify the physical units per pulse or the num-
ber of pulses per fundament
al unit (for example,
if 1 c = 1 pulse, select [1 Pulse]).
Move the cursor to the numerical value and press ENTER
to display the numerical setting dialog.
See: "Numerical Value Entry" (p .67)
The settings for physical units per pulse and pulses per
fun
damental unit are interlinked.
Setting options:(
 : default setting)
Dec Displays converted values using fixed-point
notation.
Exp Displays converted values using floatingpoint
notation.

Scaling Setting Example
For integration with a 50,000 pulse/kWh watt-hour meter:
Cond: Dec
Units: kWh
1kwh=50000 pulse
For integration with a 10 liter/pulse flow meter:
Cond: Dec
Units: L
1 pulse=10L
Combining scaling and display positioning (upper/lower limits)
To use both scaling and upper/lower display limits, set the scaling first, then
upper/lower limit values.
Saving and loading data with scaling function
When the scaling function is set to enable, scaling information as well as raw
dat
a (non-converted data) in binary format are saved. When the data saved in
the storage devices is loaded, the converted data will be displayed. The raw
data can also be observed by resetting the scaling function to OFF.
