SCALING YOUR METER
Scaling your meter without a sensor or a signal source connected is easily accomplished by using
one of the calculated scale factors as shown in Table below.
Scaling to Display Engineering Units
These calculated scale factors are the numbers that your meter would display if you connected a
signal source.
You must complete the procedure for preparing your meter for Scaling as described in
Section 16.4
" IN.SC.OF " INPUT SCALE & OFFSET, " MANUAL ". Failure to complete this procedure will result in
erroneous readings.
Input Signal Range 0-20mA 4-20mA +50mV +500mV 0-20mV 0-30mV
Scale Input 1 Value 000000 000000 -50000 -50000 000000 000000
Scale Input 2 Value 020000 020000 050000 050000 020000 030000
Input Signal Range 0-50mV 0-100mV 0-1V 0-5V 1-5V 1-6V
Scale Input 1 Value 000000 000000 000000 000000 010000 010000
Scale Input 2 Value 050000 100000 100000 050000 050000 060000
Input Signal Range 0-10V 0-50V 0-100V +5V +50V
Scale Input 1 Value 000000 000000 000000 -50000 -50000
Scale Input 2 Value 100000 050000 100000 050000 050000
Table 16-2. Factory Calculated Scale Factors Table
For the purpose of this procedure, we will use an input of 0-50 mVdc and scale the meter to display
0 to 2500.0. The calculated scale factors can now be used to scale your meter to display in
engineering units using Input Scale and Offset (" IN.SC.OF ") as follows:
Record your " INPUT1 " and “ READ 1 " numbers, and your " INPUT2 " and " READ 2 " numbers, record
them below and proceed as follows:
Example
INPUT1 = 000000
READ 1 = 000000
INPUT2 = 050000
READ 2 = 025000
