Calibration

Guidelines

CAUTION
If adjustments are made to the real-time clock, the calibration due date will be
invalid for the XD and X5.
Recalibrate the detector immediately.
When calibrating the sensors, adhere to the following guidelines:
•

•
Calibrate only in a clean atmosphere that is free of background gas. Do not
operate the station in a hazardous area. Failure to adhere to this guideline
can result in possible personal injury and/or property damage.
•
Honeywell Analytics recommends using premium grade calibration gases
and cylinders that are certified to National Standards. The calibration gases
must meet the accuracy of the detector.
•
Do not use a gas cylinder beyond its expiration date.
•
All calibration cylinders must be used with a demand flow regulator and
must meet the following maximum inlet pressure specifications:
i. Disposable cylinders 0-1000 psig/70 bar
ii. Refillable cylinders 0-3000 psig/207 bar
•
Refer to the detector user manual for recommended calibration
frequencies.
