Product Overview
The Testo 400563 4354 IAQ Kit is a versatile instrument for environmental measurements. Familiarize yourself with its components:
Figure 1: Testo 435-4 IAQ Meter. This image displays the handheld meter, featuring a large digital display at the top showing readings like "1037 ppm" and "934.4 m³/h". Below the screen are several control buttons: three orange circular buttons at the top, followed by two grey arrow buttons (up and down), another grey circular button, and finally a power button with a power symbol. The device has a sleek, ergonomic design with a black body and silver-colored accents.
Key Components:
- Display: Large LCD for clear reading of measurement values and menu navigation.
- Control Buttons: Intuitive buttons for power, navigation, selection, and function activation.
- Sensor Input: Port for connecting various probes (e.g., CO2, humidity, temperature).
- Battery Compartment: Located at the rear for power supply.
Setup
1. Battery Installation:
- Locate the battery compartment cover on the back of the device.
- Open the cover by sliding or unscrewing it (refer to specific model instructions if screws are present).
- Insert the required batteries (e.g., AA or AAA, typically 3 or 4) ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
2. Probe Connection:
- Connect the desired measurement probe (e.g., CO2 probe, humidity/temperature probe) to the designated input port on the device.
- Ensure the connection is firm and secure to prevent inaccurate readings.
Operating Instructions
1. Powering On/Off:
- To power on, press and hold the Power button (usually marked with Ⓢ) until the display illuminates.
- To power off, press and hold the Power button again until the display turns off.
2. Taking Measurements:
- Once powered on and a probe is connected, the device will typically display real-time measurements for the connected parameters (e.g., CO2 in ppm, Temperature in °C/°F, RH in %).
- Position the probe in the environment you wish to measure. Ensure proper air circulation around the sensor for accurate readings.
- Allow a few moments for readings to stabilize, especially for CO2 and humidity.
3. Navigating Menus and Saving Data:
- Use the Up/Down arrow buttons to navigate through different measurement modes or menu options.
- Press the Enter/OK button (often a central circular button) to select an option or confirm a setting.
- To save a measurement, look for a Save or Memory button/option. Follow the on-screen prompts to store data.
- To recall saved data, navigate to the Memory or Recall menu option.
Maintenance
1. Cleaning:
- Wipe the device casing with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Ensure no liquid enters the sensor openings or electrical connections.
- For probes, follow specific cleaning instructions provided with the probe itself.
2. Battery Replacement:
- Replace batteries when the low battery indicator appears on the display.
- Always use new batteries of the specified type.
- Dispose of old batteries according to local regulations.
3. Calibration:
- Regular calibration is essential for maintaining measurement accuracy.
- Refer to the device's on-screen calibration menu or consult Testo's official support for recommended calibration intervals and procedures.
- Some probes may require specific calibration gases or humidity standards.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly installed batteries. | Check battery polarity; replace with new batteries. |
| Inaccurate readings. | Sensor dirty, damaged, or out of calibration; improper probe connection. | Clean sensor; ensure probe is securely connected; perform calibration. |
| Display shows "Error" or "---". | Sensor malfunction; out of measurement range; internal error. | Check probe connection; move to an environment within measurement range; restart device; contact support if persistent. |
| Cannot save data. | Memory full; incorrect save procedure. | Delete old data; refer to operating instructions for saving data. |
