Overview
The DB25-DT900 is a small, lightweight, battery-powered Handheld measurement instrument manufactured by the DUBAN brand. It is mainly used for elevator adjustment, maintenance and inspection work, and has two display channels and corresponding test modules.
Features
It can store 20 sets of data, including CH1 value, CH2 value and MAX Maximum, and supports customized larger storage capacity.
2. With MAX Maximum hold function.
3. Support the average calculation function, which can calculate the average value of up to 200 measurement values, and the measurement time interval is 10ms.
4. With battery low voltage prompt function.
5. With distance measurement function.
6. Support Bluetooth printer function, can directly print measurement data.
7. It can be connected to the computer through a USB data cable or a Bluetooth adapter to achieve data transmission.
Principle
The instrument adopts contact measurement method. When in use, install the circumferential speed ring or speed contact head on the instrument, then gently stick and press the surface of the measured object for measurement. The instrument senses the linear speed or speed of the measured object through the contact part, and displays the measurement data on the liquid crystal display.
Applications
Elevator adjustment, maintenance, and inspection
Steps
1. Install the battery: Open the battery cover on the back of the instrument, install 2 14500 lithium batteries according to the instructions of the positive cathode, and then cover the battery cover.
2. Install the measurement parts: Install the circumferential speed ring or the speed contact head to the instrument shaft and use the screw driver to tighten the screws.
3. Carry out measurement: gently press the circumferential speed ring or the speed contact rod against the measured body (the force does not exceed 5kg), and keep a reliable grip for measurement.
4. Data management: Data can be viewed and stored through the instrument function, or connected to a printer or computer for printing and transmission.
Notice
* When installing the battery, pay attention to the positive cathode, and installing it upside down may cause instrument failure.
When installing the circumferential speed ring, ensure that the installation position is correct and the contact is reliable to prevent accidents caused by peeling during the test.
When testing, pay attention to the relative angles of the test and firmly grip the test parts.
When the test speed reaches or exceeds 1000m/min (10000rpm), it cannot be used hand-held and the instrument must be fixed.
* When the battery voltage is too low, a prompt symbol will appear on the display, and the Power Adapter should be used to charge at this time. When charging, the red light is on to indicate that it is charging, and the green light is on to indicate that it is fully charged. Unplug the adapter after it is fully charged.
* Although the distance measurement range can reach 5000mm, the numerical accuracy after exceeding 999mm cannot be guaranteed.
