Enter the ‘Initial Reading’ in volts for linear gage factor calculation or the value of coefficient C for
polynomial calculation. You can enter the value in fixed point format but while recalling this value the
indicator will show the same value in floating point format. For example if you enter ‘Initial Reading’ as
1955.1 subsequently when you recall this channel the indicator will display the same value in floating
point format as 1.955E+03. The next prompt on display is
GF ? 1.0000E+00_
Enter the ‘gauge factor’ in floating point format for linear gage factor calculation or value of coefficient B
for polynomial calculation. Remember, the mantissa should not exceed five digits. You can enter the
minus sign if required before the number and also after the exponent symbol ‘E’. Display will now prompt
X2 ? 0.0000E+00_
Enter the value of coefficient A for polynomial calculation. Other wise set this value to 0 for linear gage
factor calculation.
The next prompt on the display is for decimal places.
DP ? 0_
The display is prompting you to enter the number of digits to the right of the decimal point to be shown
while displaying the parameter value in engineering units. For example you might want to show pressure
for a 1 kPa pressure transducer as 1.000 kPa and a 10 kPa pressure transducer as 10.00 kPa. In the first
case you would enter the value of ‘DP’ as 3 and in the second case as 2.
That completes all the information for setting up a transducer. As soon as you enter the decimal places
the display prompts you to enter the next channel number to setup.
You will notice that by default the last programmed channel number appears on the channel number
prompt. For example, if you had just programmed channel number 5, the channel number prompt will
appear as
Ch # ? 5_
Should you want to verify the entry that you have just made, press enter and you can verify each of the
entered parameter for channel 5.
To exit setup mode press ‘ESC’ key at the channel number prompt. The display will flash
* SETUP ENDS *
and then the indicator will reboot (i.e. restart) in the normal measurement mode.

Erasing setup data for a single channel
At times you may want to remove the calibration coefficients of a single transducer or some of the
transducers individually from the setup memory. If you are replacing one transducer with another, setting
the same channel number with the calibration coefficients of the replacement transducer will
automatically erase the old data. However, if the channel number is to be left blank (i.e. you do not wish
to setup any transducer in that channel) you need to erase the existing transducer data.
To erase any individual channel go to channel number prompt in the setup mode. Enter the channel
number from which you want to erase the transducer coefficients. The display will show the units prompt
and the last programmed units symbol.
UNITS ? kPa_
Press the ‘CE’ key (clear entry), the display will prompt to confirm whether you really want to delete the
transducer data.
