indicator as shown on the right. The instrument can be charged with power on or off. For fastest charging of the Halimeter PLUS do not connect any other USB devices to the charger. NOTE: The internal batteries must have a charge to maintain the sensor bias voltage and minimize sensor warmup time. -
Page 15: Section 4 - Breath Sampling Considerations
Section 4 – Breath Sampling Considerations The Halimeter PLUS is designed to reliably measure VSC (Volatile Sulfur Compound) concentrations as part of a total program for the treatment of halitosis. Along with a thorough history and physical examination of the patient, the quantitative nature of ... -
Page 16: Sample Interferences
4.1 SAMPLE INTERFERENCES Part of ensuring accurate sample readings is minimizing sensor interferences that may result in false readings. One of the most common interferences to the Halimeter® PLUS sensor are vapors present in MOUTHWASH. The presence of residual mouthwash in the mouth will produce a false Halimeter®... - Page 17 3) When ready to collect sample, the end of the sample straw should be inserted into the patient’s mouth at a depth of approximately 1-2 inches (25-50mm) resting on the back of the tongue. The lips should be almost closed allowing for a slight gap between the lips and the sample straw.

Page 18: Section 5 - Taking Breath Samples
Section 5 – Taking Breath Samples After powering up the Halimeter PLUS, select MEASURE from the MAIN MENU by pressing the RIGHT ARROW button. This will open SENSOR STABILIZING MODE and a 5-minute timer will elapse. Upon the timer elapsing, the instrument will automatically enter OFF MODE. -
Page 19: Taking Samples
5.2 TAKING SAMPLES After zeroing the display, the instrument is ready for sampling. The following steps detail the sample procedure: 1) From ON MODE, press the ENTER button. This will advance the instrument to SAMPLE MODE starting a series of 3 sample cycles where 3 separate breath samples will be taken. -

5) This HOLD/SAMPLING cycle will repeat for 3 total samples. A new PEAK value will be added for each completed SAMPLE cycle above the timer field. At the end of the third SAMPLE cycle, the instrument will return to ON mode and the breath value display will show the average of the 3 PEAK sample values as indicated by “AVG”... -
Page 21: Section 6 - Data Storage And Access
Section 6 – Data Storage And Access Sample data can be stored on standard SD card media (a 32 GB card is provided with the instrument). Data is saved to the SD card automatically in ON mode and SAMPLE mode at a rate of one sample per second when AUTO SAVE is enabled (this is the default status on power up). -

Page 24: Section 7 - Calibration
Section 7 - Calibration Periodic calibration of the Halimeter PLUS is required to compensate for decreased sensor sensitivity and maintain accuracy of readings. The frequency of calibration is a function of instrument use and the concentrations of volatile sulfur compounds (VSC) to which the sensor is exposed. - Page 25 1) Navigate to the MAIN MENU by pressing the STOP button successively until the MAIN MENU shown to the right is displayed. 2) Press the UP or DOWN ARROW buttons to move the cursor to highlight “Setup” then press the RIGHT ARROW button to enter the SETUP MENU.
- Page 26 When the value is correct, press the ENTER button to begin calibration sampling. 6) The screen shown on the right will now open showing the CAL timer (red arrow), the active ppb reading value and the peak ppb value. At this point, the breath subject should place the sample straw in his/her mouth and present a sample in the manner described in section 4.2.

8) Firmly grasping the sensor body as shown in Figure 8-10 below, slowly tilt the furthest edge of the sensor body away from the manifold and toward you as shown in Fig 8-10. Don’t attempt to pull the sensor straight out or rotate the sensor in the manifold. The senor should release from the manifold as shown in figure 8-11. - Page 30 2) Position the rear panel so the top and side edges are aligned with the instrument case as shown below in Figure 8-14. Secure with the panel screws. NOTE: screws should thread easily into the screw holes. If there is any significant resistance when threading the screws, STOP, back the screw out and re-align the panel holes with the threaded holes.
