accuracy. Do not operate the instrument in the high temperature, high humidity environment. Especially, do not store the instrument in the wet environment, as the instrument performance may deteriorate if being wetted. Clean the instrument enclosure with a wet cloth and a gentle detergent, and do not use abrasive agents or solvents.
PRODUCT INTRODUCTION Overview ● The automobile diagnostic multimeter is a hand-held new diagnostic oscillometric multimeter integrating digital oscillo- scope, digital multimeter, which is designed with the embed- ded digital control technology. ● The multimeter mode can measure the AC / DC voltage and current, resistance, diode forward voltage drop, on-off and frequency.
Button function Press for power-on, press for about 0.3 seconds to turn off the power when it is Power key on, and long press 3 seconds to reset the instrument. HOLD Pause Hold / Measurement key. Direction Select the functional items. button Return key.
OPERATIONS INSTRUCTION Functional ● The instrument is equipped with a power switch and the operation automatic sleep function. The automatic sleep time can be set guidelines to 1-30 minutes. The key tone of the instrument can be set to turn on and off, but the warning tone cannot be turned off. The brightness of the screen can be set.
Enter the function item, displayed as shown below: ● Voltage ( DC) 0.00V <HOLD>Hold <F1>Zero <Fn>Function Mode <F2>PULL DOWN ● The current measured value is displayed. If the voltage fluctu- ates, press the [HOLD] key to maintain the display status. If there is no voltage signal, the displayed value is non-zero, the red and black probe can be shorted, and press the [F1] key at the same time to perform the quick zeroing operation.

In the process of voltage signal measurement, the instrument ● automatically changes the range and the maximum measur- able voltage signal is 1000V; Current ● Measure the current below 200mA, insert the red probe into measurement the green “mAuA” jack, and insert the black probe into the “COM”...
Press [F2] key and switch to detect high current mode as ● shown below: Ampere(DC) 10A(Yellow) 0.00A <HOLD>Hold <F1>Zero <Fn>Function Mode <F2>20A/mA In the high current mode, the maximum measurable current is ● 20A and the maximum measurable continuous current is 10A. There is 15A 30V self-recovery fuse inside, which can protect the instrument from damage due to excessive current in the use of vehicle detection.
Resistance 0.00Ω Diode: <HOLD>Hold <F1>Zero <Fn>Function Mode ● The instrument detection resistance and the diode are two-in-one function display. Press [Fn] key to switch the display mode. When measuring the resistance, the resistance can be set as the main display; when measuring the diode, the diode can be set as the main display;...

Frequency Insert the red probe into the “V” jack and the black probe into ● measurement the “COM” jack; ● The red probe is connected to the signal to be tested, and the black probe is connected to the ground line of the signal source to be tested.
OTHER PROBLEMS Software ● The instrument can update the application software with upgrading MicroSD card and copy the updated file to SD card. Insert the instrument SD holder and restart up. If the instrument detects an available upgrade file, it will be displayed on the screen and press [OK] directly.
