SENVA SENSORS 153-0048-0A Gas Sensors

Product Information

Specifications

  • Model: Gas Sensor XYZ
  • Power Source: 2 AAA batteries
  • Detection Range: 0-100 ppm
  • Calibration Modes: Baseline and Span
  • Indicator Lights: Green, Orange, Red

Product Usage Instructions

Hold down the left + right buttons for 5 seconds. The buzzer will begin to sound and the LED will blink Green 1 time every 2 seconds to indicate successful entry into calibration mode.

  • Hold down the left button (sensor 1) or right button (sensor 2) for 5 seconds.
  • The buzzer will begin to sound and the LED will blink orange: 1 time for sensor 1, or 2 times for sensor 2, every 2 seconds.
  • IMPORTANT: Calibration requests take place instantly. Ensure the sensor is in a stable environment without gas for at least 15 minutes before applying a baseline calibration.
  • Hold down the left button for 5 seconds to activate baseline calibration.
  • The buzzer will sound and the LED will blink 3 times to indicate the status of the request. Red LED if failed, Green LED if succeeded.
  • IMPORTANT: Check the provided table to ensure the correct gas is being used.
  • Apply gas until the output stabilizes, which should take 60-90 seconds.
  • Hold down the right button for 5 seconds to activate span calibration.
  • The buzzer will sound and the LED will blink 3 times to indicate the status of the request. Red LED if failed, Green LED if succeeded.

NOTE: If calibration is done incorrectly, go back through steps 1 and 2, then hold down the left + right buttons for 10 seconds to reset to factory calibration. The buzzer will sound and the LED will blink 3 times to indicate the status of the request. Red LED if failed, Green LED if succeeded.

FAQ

  • Q: How often should I perform calibration on the Gas Sensor XYZ?
  • A: It is recommended to perform calibration at least once every month for accurate results.
  • Q: What should I do if the LED blinks red during calibration?
  • A: If the LED blinks red, it indicates a failed calibration. Please retry the calibration process ensuring the correct steps are followed.

EQUIPMENT

  • Contact Senva (866-660-8864) to buy calibration gas kits and shrouds which will contain all necessary equipment for each sensor.
  • If using gas not provided by Senva, please ensure your calibration gas is not expired that it meets the below requirements for concentration (PPM or %) and you are using a 0.5 LPM regulator. It is also recommended to calibrate using Senva’s gas shrouds to ensure proper gas allocation.

Enter Calibration

  • Hold down the left + right buttons for 5 seconds. The buzzer will begin to sound and led will blink Green 1 time every 2 seconds to indicate successful entry into calibration mode.

Choose Sensor

  • Hold down the left button (sensor 1) or right button (sensor 2) for 5 seconds.
  • The buzzer will begin to sound and the LED will blink orange: 1 time for sensor 1, or 2 times for sensor 2, every 2 seconds.

Apply baseline calibration

  • IMPORTANT: Calibration requests take place instantly. When calibrating the baseline, ensure the sensor is in a good stable environment without gas for at least 15 minutes before applying a baseline calibration.
  • Hold down the left button for 5 seconds to activate baseline calibration.
  • The buzzer will sound and the LED will blink 3 times to indicate the status of the request. Red LED if failed, Green LED if succeeded)

Apply Span Calibration

  • IMPORTANT: Check the table above to ensure the correct gas is being used.
  • Apply gas until output is stabilized, should take 60-90 seconds.
  • Hold down the right button for 5 seconds to activate span calibration.
  • The buzzer will sound and the LED will blink 3 times to indicate the status of the request. Red LED if failed, Green LED if succeeded)

NOTE: if calibration is done incorrectly go back through steps 1 and 2 then hold down the left + right buttons for 10 seconds to reset to factory calibration.
