The DB25-DT900 is a small, lightweight, battery-powered, hand-held tachymeter. It is used for the adjustment, maintenance and inspection of elevators. It contains two display channels and the corresponding test module.
Features
It can store 20 sets of data, including CH1 value, CH2 value, and maximum value. Larger stocks can be ordered.
Maximum value hold function.
The average value calculation function can calculate the average value of up to 200 measured values with a measurement interval of 10ms.
Battery low Voltage reminder function.
Distance measurement function.
Bluetooth printer function, direct printing of measurement data.
It can be connected to the computer through a USB cable or Bluetooth adapter to realize the data transmission function.
Precautions for use
1. Power supply
High Precision Contact Linear Velocity Meter DB25-DT900 Before using the instrument, install 2 14500 lithium batteries.
(1) Open the battery cover on the back of the instrument.
(2) Install the battery in the battery position according to the positive and negative poles, and note that if the polarity is reversed, it will cause the instrument to malfunction.
(3) Close the battery cover. When the battery Voltage is too low and the battery symbol appears on the display, use the power adapter to charge. When the charge is indicated
When the light turns red, it means that it is charging; When the indicator light is green, it means that the battery is fully charged. Please unplug the adapter when fully charged.
2. Install the circumferential speed ring and the speed contact head
When installing the circumferential ring, insert the shaft of the tachometer into the top of the measuring part and tighten the screws using a screwdriver. Installation in the wrong location or
Unreliable contact can cause the tachometer and circumferential ring to fall off during the test, and may even cause an accident.
3. Test precautions
Gently press the circumferential speed ring or the speed contact rod (the force should not exceed 5kg) to the test object, and pay attention to the relative angle of the test during the test
Grip the test part reliably and securely.
4. Precautions for the scope of the test
When the test speed is 1000m/min (10000r/min) or higher, this tachometer cannot be used hand-held. At this time, the instrument is fixed.
