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
Power-down the unit. Remove the compartment
cover. Plug in and insert the module. Reinstall cover. Power-on the unit. Calibrate.
