Calibrating the Test Tool

Before shipment, each test tool is calibrated to work with the remote unit shipped
in the same package. If you want to use your test tool with a different remote, you
must perform a self-calibration to store the new calibration parameters in the test
tool. The test tool stores the calibration data in non-volatile memory that is
maintained by a lithium battery. You can calibrate your test tool to work with two
different remotes. Self-calibration is not required when you switch between link
interface adapters.
To ensure maximum accuracy of test results, perform the self-calibration every
30 days. Fluke Networks recommends factory calibration once a year to ensure
that the test tool meets or exceeds the published accuracy specifications. To return
a unit to Fluke Networks for calibration, call an authorized Fluke Networks
Service Center for return instructions.
All DSP-4000 Series test tools use the DSP-4000 calibration module.
Allow a 1 minute warm-up time before performing a self-calibration.
Perform the self-calibration only after the test tool has warmed up to
an ambient temperature between 10° C and 40° C (50° F and
104° F).
