2.2.5 Cal Setup Menu

The CAL SETUP feature supports pushbutton calibration of zero and span values. This feature should only be utilized when there are no other zero/span controls within the monitoring system since it is inappropriate to calibrate a signal at more than one point. Therefore, if calibration will be performed at another transmitter or monitoring device, the CAL SETUP feature should not be used.

The CAL SETUP menu allows entering the correct Zero Gas & Span Gas set-point values needed to calibrate the channel. These are entered in the same engineering units as input range.

2.2.6 Calibrate Input Menu

The CAL SETUP flow chart (shown in Figure 2-6) is designed to make calibration quick, easy and error free. A successful ZERO and SPAN calibration requires only a few keystrokes. Optional 4-20mA outputs (if equipped) transmit 1.5mA during calibration and 4mA during the subsequent CAL DELAY to prevent triggering external alarms during calibration. Local HA40 alarm relays are inhibited during calibration. Unintentional calibrations may be reset using the Set UNITY menu item. Set UNITY resets Cal OFFSET to 0 & Cal GAIN to 1 which is useful for returning the calibration to a known starting place. Sensor aging may be monitored by recording zero and span readings at Unity Gain when the sensor is new, and again later when degradation may have occurred. CAL MODE automatically exits if no keystroke is detected after 5 minutes.

Use the following step-by-step procedure to perform ZERO and SPAN calibrations.

1.To enter the CAL SETUP from any data display, press the dual purpose down arrow / CAL key then use the up/down arrow keys to select the channel to calibrate.

2.Stimulate the monitor to be calibrated with an appropriate ZERO calibration standard. Observe the screen’s live reading and when it is stable press the Edit key to perform the ZERO calibration.

3.If the ZERO calibration is successful, CAL SETUP automatically proceeds to the SPAN check.

4.Apply the correct SPAN calibration standard. After the reading is stable, press the Edit key to perform a SPAN calibration.

WARNING

The SPAN calibration standard used must match the value specified since this is the reading the HA40 will indicate after a successful SPAN calibration. The SPAN calibration value may be edited if it becomes necessary to apply a different calibration standard to set SPAN (see Span Calibration in section 2.2.5).

5.If the SPAN calibration is successful, the display flashes “REMOVE CAL GAS” and starts the CAL DELAY.

6.CAL SETUP is complete after the end of the CAL DELAY.

The flow chart in Figure 2-6 illustrates the above procedure. UP, CAL, Next & Edit labels indicate keystrokes (down arrow/CAL is a dual purpose key). The CAL SETUP information screen (top of the chart) is available for advanced users to see Offset / Gain calibration constants and live analog to digital converter (A/D) counts. Span set point calibration values may also be edited from this screen. Holding the up key, for 5 seconds during CAL SETUP, displays this screen.

HA40 specifications

The Honeywell HA40 is an advanced air quality monitor that offers a multitude of features designed to provide users with accurate and real-time data regarding their indoor air conditions. As part of Honeywell’s commitment to improving the environments where people live and work, the HA40 stands out as an essential tool for continuous air quality assessment.

One of the main features of the Honeywell HA40 is its capability to measure a variety of air pollutants. It provides real-time readings of particulate matter (PM2.5 and PM10), volatile organic compounds (VOCs), carbon dioxide (CO2), and formaldehyde levels. This comprehensive monitoring allows users to understand their air quality better and take appropriate actions to improve it.

The HA40 is equipped with advanced sensor technology that enhances its accuracy and reliability. The device utilizes laser scattering methods to precisely detect particulate matter, which offers detailed information on the concentration of airborne particles. Additionally, its integrated VOC sensor leverages photoionization to deliver quick and exact results concerning the presence of harmful compounds in the air.

Another notable characteristic of the Honeywell HA40 is its user-friendly design. The device features a clear, intuitive display that presents data in an easily understandable format. Users can quickly assess air quality levels at a glance and receive alerts when pollutants exceed predefined thresholds. Furthermore, the HA40 is compact and portable, making it suitable for both home and office use.

Connectivity is another strong point of the Honeywell HA40. The device can be connected to a smartphone application, enabling users to monitor air quality remotely. This app provides additional functionalities such as trend analysis, historical data tracking, and personalized recommendations for improving indoor air quality.

Power efficiency is also a priority with the HA40, featuring a low-power design that extends battery life and reduces the frequency of recharging. This makes it convenient for users who wish to place the monitor in various locations without the hassle of constant maintenance.

In summary, the Honeywell HA40 represents a significant advancement in indoor air quality monitoring. With its accurate sensors, user-friendly interface, and connectivity options, it empowers users to maintain a healthier living and working environment.
