Why calibrate?• Calibration introduces a

known substance into the detector for identification.

• After the VaporTracer2 identifies the calibrant, the software will adjust the positions of all substances.

• The VaporTracer2 must be calibrated for accurate detection.

Calibration

When do you calibrate?• After powering up• After changing modes• At the beginning of each

shift• When the unit is moved • At higher elevations• When atmospheric

conditions change (humidity, pressure)

Preventive Maintenance

• A substance must give off a sufficient amount of vapor to be detected.

• Heat increases the amount of vapor that is emitted.

• The vapor must be contained (vapor release point).

Vapor SamplingMiscellaneous Features

• After attaching the vapor plate, the unit will need 15 minutes to adjust temperatures.

• Perform calibration.• MENU 1 Highlight CAL INT.• Verify calibration using the

Check Sample.

Vapor Calibration and VerificationMiscellaneous Features
