The 8-speed selection switch can be selected according to the requirements of the time. If the small switch is pulled to “ON” (open), it will take time to stop. If the second or multiple files are pulled to “0N” at the same time, an error will occur at the timing. The 8-speed switch is in the off position and the instrument does not work. Considering that the operator has different requirements for the selected time, the manual file is set in the "1" file, and the user can turn off the power according to his own time.

1. Work instruction and under-voltage indication To ensure the efficiency of the operator and make the instrument more practical, the TMP-1500 small sampler has a working indication and an under-voltage indication, which can clearly tell the operator when to replace the dry battery. The red light is on. When the voltage is lower than 6.3V±0.3V, the red light is automatically turned off, indicating that the battery is under voltage. This is also an essential protection for nickel-separated batteries.
2. The power supply instrument is equipped with a “charge-regulation” dual-purpose power supply. When the power is normally sampled, the power switch position is in the “regulated” position. At this time, the 8C DC voltage is output. For charging, the power switch position is in the “charge” position. At the same time, the sampler switch is turned off, and it can be automatically charged. When the battery voltage of the sampler is charged to the rated value, the charger indicator light is extinguished by itself, indicating that the charging is over.
Out-of-sampling, it is convenient to use a dry battery without AC power. The 6#5# dry battery is generally used for about 4 hours, and the nickel-free battery can be used for about 8 hours. If the sampler indicator is off, it means that the undervoltage is required, then the dry battery needs to be replaced. If the nickel-free battery is under voltage, it needs to be charged.

Second, the use of maintenance
1. Remove the sampler battery cover, place the No. 5 dry battery or rechargeable battery for 6 sections, cover the cover, and then gently pull the timing adjustment cover to the left to select the desired timing (such as the "2" position. At this time, 5 minutes) push the sampler power switch up, the red indicator light is on, and the instrument starts to work. Timing accuracy can be corrected with a stopwatch.
Note: If it is not used for a long time, the battery should be taken out to prevent the liquid from escaping when the battery deteriorates.

Our factory and the Beijing Institute of Labor Protection Science and Technology carry out extensive technical cooperation. From the technical performance of the instrument to the production inspection of the product, the specific guidance of the scientific research institute makes the product have a high technical level and satisfactory use effect. In March of 1989, it was judged by the World Health Organization, the Department of Health and Epidemic Prevention and the instrument experts, and was ranked first among similar instruments.
Our factory has been examined and approved by Jiangsu Province and Yancheng Metrology Bureau, and has obtained the measurement certificate, the quantity of work certificate (1991) No. 103 and the manufacturing measurement instrument license, and the certificate number (92) to make the system of the word 09250102.
