2.3.2 Scales tab

When the Scales tab is selected, the Scales window opens.
This second page lets you parameterize the following options:
Input range or scale: this window remains empty when the input ranges have fixed scales. You can
specify a scale for the inputs that are not fixed (those of clamps, for example). For example, 1 V =
1,000 A.
Input offset: this option is proposed only with models that provide this possibility. The value of the
offset, which can be positive or negative, is applied during the transfer of the data to the PC.
Linearity Scale: for instruments that allow a user specified linearity adjustment this control will be
displayed. The Linearity adjustment allows you to specify a scale to be used for the measurement
results. The linearity is applied to measurement values when measurements are downloaded from
the instrument (both real-time and recorded). A scale is specified by entering the Beginning and End
native measurement values and their corresponding display (scaled value). For example if we have
a sensor that outputs 4mA @ 100PSI and 20mA @ 200PSI you would specify the following
Starting: 4
Ending: 20
Displayed value (low): 100
Displayed value (high): 200
A 1 to 1 scale can be specified using 0 = 0 and 10 = 10 for the Beginning and End values. Allowable
values for the Beginning and End fields are integer (whole) numbers in the range of -10000 to
10000. Displayed fields can contain floating point (rational) numbers in the range of +/- 30000E+/-
127.
Units: for instruments that allow a user specified measurement units this control will be displayed. It
allows you to over-ride the default measurement units of the instrument. You can specify up to four
characters for the units to be associated with the channel.
Temperature Units: the Temperature Units option is only available and displayed when configuring
a TC logger. This option allows you to select between the three temperature units (Celsius,
Fahrenheit and Kelvin) in addition is allows you to display the raw voltage measurement of each
input.
TC Type: the TC Type option is only available and displayed when configuring a TC logger. This
option allows you to select between the Thermocouple types supported by the instrument. This
selection will apply to all TC inputs. Multiple TC Types can not be used at the same time with the
Simple Logger II.
Filter: the Filter option is only available and displayed when configuring instruments that support
input filtering. This option allows you to select the level of filtering (averaging) of measurements.
Filtering is performed by averaging the last x values measured on an input. Next to each filter name
(in parenthesis) is the number of samples averaged. A Filter of None provides no filtering and simply
results in individual measurements being stored.
