Decimal Places: From the pull-down menu, select the

number of decimal places to the right of the decimal

point that should appear in the historical data and in the

numerical data field at the bottom of the bar graph.

Calibrate: The “Calibrate” button provides a simple 4-step process for calibrating

the logger to a particular sensor. Click the Calibrate button and follow the menu

instructions.

Click on the High EU field and enter the

high engineering unit that will be used to

calibrate the logger, not the highest reading

the sensor can output. In this example, a

pressure of 100 psi is used to calibrate

the logger, even though the sensor can

measure up to 200 psi.

Click Next.

Place the sensor in the condition that will

cause it to output the level corresponding

to the high EU entered in the previous menu.

Wait for the data reading to stabilize.

Click Next.

Click on the Low EU field and enter the

low engineering unit that will be used

to calibrate the logger, not necessarily

the lowest reading the sensor can output.

In this example, the value is zero psi.

Click Next.

Place the sensor in the condition that will

cause it to output the level corresponding

to the low EU entered in the previous menu.

Wait for the data reading to stabilize.

Click Next to complete the calibration.
