1-2. Warning Warning Do not use any adaptors except supplied original AC adaptor. Do not use in explosive atmosphere. Do not use the device where combustible and/or explosive gasses exist. The device is not designed for explosion proof. Do not dismantle the base unit.
1-3. Cautions Cautions Do not install, use, or store the unit at a place where: Ambient temperature is not in the range of -10 to 40 degree in C. (14 to 104 degree in Ambient humidity exceeds 90%R.H. Condensation occurs due to rapid temperature change. Corrosive and/or explosive gases exist.
2. General Description Handheld Odor Meter is the most popular simplified tool for odor analysis which enables to show the relative odor strength numerically by comparing odor gases and purified air. The reading shown on the display is calculated based on our original principle. With the installation of data filing software, measured data can be transferred to PC in easy steps.
2-1. Features 2-1-1. LCD Display Name Function Blinks for about 10min for initializing when the unit is turned on. Ready ① Start measuring when it stops blinking. Displays odor strength in numeric value from 0 to 999. Odor Strength ② Start blinking when overflowed.
2-1-2. Base Unit Name Function Hold 3 seconds for “peak-hold function”. (See 3-3.) ① Hold and turn on the device at the same time to set calendar. Select sampling rate. (See 3-2.) ② Set calendar. Use for “zero-point function". (See 3-4.) ...
2-2. Accessories Name Function AC Adaptor Connect to the unit during the measurement if necessary. Air Purifying Unit Attach to the unit for “zero-point function”. (See 3-4.) Exchange activated carbon when deodorization using air Activated Carbon purifying unit is not effective. Replace filter when deodorization using air purifying unit is not Replacement Filter for Air effective.
3. Measurement 3-1. Real-time Sampling Mode 3-1-1. Measurement Preparation 1. Place filter to suction nozzle. 2. Attach suction nozzle to the unit before measurement. 3. Use “AA” alkaline batteries or AC adaptor. 4. Turn on the unit at clean ambient. It takes about 10 min for the unit initializing and start measuring.
3-1-2. Measurement 1. Turn on the unit and wait for about 10 minutes until “Ready” stop blinking and the initializing is done. 2. Start measuring. 3. Use data filing software if necessary. 4. Turn off the unit when odor strength shows close to “0”. 3-2.
3-2-3. Memory Overflow Memory overflow occurs when the internal memory is full. If there is no space remained, calendar on LCD display starts blinking and data number becomes “0”. To delete saved memory, press at the same time while the unit is turned off.
3-3. Peak-hold Function Press for over 3 seconds during Real-time sampling. By using this function, the highest value of odor strength keeps being displayed until the unit measures higher value. NOTE Press for over 3 seconds again to cancel the function. NOTE The function is not displayed on the saved data.
How to Install USB Drivers Software Install USB Drivers software before connecting USB cable to PC. 1. Download the latest software from the link as below. https://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx 2. Install the software.
