What is fresh air calibration?

Fresh Air Setup (FAS) Fresh air setup allows an instrument sensor to establish a zero baseline, but within only a limited window of correction. If sensor readings are not within acceptable range relative to zero, FAS will fail and full calibration is recommended.

What is the difference between a bump test and calibration?

The main difference between a bump test and calibration is that a bump test determines whether a DRPGM can detect if a possibly hazardous gas is present, while calibration checks that equipment is accurate.

What’s the difference between bump test and calibration?

A: A bump test is a very brief exposure of a monitor to a gas to help verify that the sensors respond and the alarms are functioning. A calibration is performed by exposing the monitor to a certified concentration of gas for a given time to help verify it provides an accurate reading.

How often does a gas detector need to be calibrated?

every six months
If a gas detector has been subject to high gas concentrations or unusual conditions, it is generally recommended that a bump test or calibration be performed. At a1-cbiss, we recommend that gas detection equipment is calibrated at least every six months for a reliable performance.

How often do you have to bump test a gas detector?

They require a bump testing frequency of 6 months or less to ensure performance is consistent. Calibration is only necessary if bump testing indicates the sensor is out of specification. Electrochemical sensors tend to drift over time and require bump testing every 3 to 6 months.

How do you bump a 4 gas monitor?

To do this, put the gas detector into bump test mode, then apply the gas. The gas detector will either cycle through each individual sensor or do them all at once, depending on the gas detector’s settings. After the test is complete, the monitor will display results, showing whether it passed or failed the bump test.

What is calibration test?

Calibration is the process of configuring an instrument to provide a result for a sample within an acceptable range. The instrument can then provide more accurate results when samples of unknown values are tested in the normal usage of the product.

How do I calibrate my air quality monitor?

Place your Smart Indoor Air Quality Monitors side by side (around 25 cm apart) in a well-ventilated room and go to the settings> advanced parameters> name of your Smart Indoor Air Quality Monitor> advanced> calibration to launch the calibration. The calibration process takes around 8 hours.

What is the service life of an X-AM?

X-am 1700: 2 years service life from activation of the device (refer to page 11). X-am 2000depending on the device type: independent measurement of one gas up to four gases. CAUTION Indicates a potential hazardous situation which, if not avoided, could result in injury or damage to property. Can also be used to warn against any wanton actions.
