Honeywell BW Flex Series User Manual

Calibration
Perform a calibration to adjust the sensitivity levels of sensors and ensure accurate responses to
gases.
The detector can be calibrated in four ways:
l Manual calibration via the instrument's menu.
l Via the Safety Suite Device Configurator (SSDC) software.
l Via the Device Configurator (DC) app.
l Use an IntelliDoX docking module. For further reference see the IntelliDox User Manual.
CAUTION
l Move to a normal atmosphere (20.9% v/v O
2
) that is free of hazardous gas.
l Calibrate the Detector before first-time use and then on a regular schedule, depending on
use and sensor exposure to poisons and contaminants. Honeywell recommends that the
sensors be calibrated regularly and at least once every 180 days (6 months).
Details for calibration and maintenance:
l PN with W5 is Non-dispersive IR, with W6 is filtered Catalytic bead technology, with W7 is
unfiltered catalytic bead technology.
l The catalytic combustible sensor is factory calibrated to 50% LEL methane. If monitoring a
different combustible gas in the % LEL range, calibrate the sensor using the appropriate gas.
l The IR combustible sensor will be calibrated to 50%LEL methane and must only be
calibrated with methane. See "Combustible Sensor Information" on page49 for more
information. for approximate response to other target gases.
Guidelines
When calibrating the detector, adhere to the following guidelines.
l Recommended gas mixture:
CO: 100 ppm balance N
2
H
2
S: 25 ppm balance N
2
LEL: 50% LEL or 2.5% for NA (2.2% for EU) by vol. methane balance air
O
2
: 18% by volume, balance N
2
. SO2:20ppm balance N
2
.
l To ensure accurate calibration, use a premium-grade calibration gas. Gases approved by the
National Institute of Standards and Technology (NIST) improve the accuracy of the
calibration.
l Do not use a gas cylinder past its expiration date.
l Calibrate a new sensor before use. Install the sensor, activate the detector, and allow the
sensor to stabilize before starting calibration (used sensor: 60 seconds / new sensor: 5
minutes, for X1 and X2 O
2
stabilization takes 24 hours. For W5 IR Sensor, 5 minutes
stabilization is needed.
l Calibrate the sensors at least once every 180 days, depending on use and sensor exposure to
poisons and contaminants.
