1、 Product Overview

TYF-30 intelligent dust sampler menu setting, capable of recording the last sampling time, continuous sampling, intermittent sampling, intelligent power management, timely display of battery level, charging indicator, and high-efficiency hollow cup motor drive. Large LCD screen display, timed shutdown without operation, etc.

Features: Microcomputer constant current system control, LCD digital display system, menu setting, AC/DC dual-use, optional lithium battery power supply.

2、 Usage method

1. Sampling

Install the sampling head with filter membrane clamp, press the "on/off" button for two seconds to enter the power on screen, press the "cancel" button to enter the "function settings", use the up and down keys to enter the "sampling mode settings" or "system function settings". If you choose the sampling mode settings, press "confirm" and then press the "left" and "right" keys to select continuous sampling or intermittent sampling (usually continuous sampling), and press the "up" and "down" keys to select the sampling time and stop time (in intermittent sampling mode). It is recommended to shut down the system if there is no operation setting within 1-3 seconds. The backlight time should be around 5 seconds. After setting, press the "Cancel" button to enter the "Confirm" sampling time. After setting the menu once, the next time you turn it on, simply press the "Power On" button and select the desired time, then press "Confirm" to start sampling.

2. Charging

The display screen of the instrument shows the battery capacity, and charging is required when undervoltage is displayed. When charging, simply connect the battery cable to AC mains and connect it continuously with the sampler for fully automatic charging. The indicator light of the charging completed host has changed from red to green.

3. Precautions

If the battery is not used for more than 3 months, it should be recharged to ensure the service life of high-energy cadmium nickel batteries.

In air with high dust content, a sampling head with a filter membrane should be installed before starting up, otherwise dust particles entering the machine will affect the cleanliness of the air path components.
