Safety Precautions
1, WM150 allows input voltage 1-50V in SOURCE
port. When the input voltage is lower than 6V, need
to provide USB5V power supply. To ensure that the
power supply voltage is consistent, pay attention to
the positive and negative polarity of the power
supply when accessing.
2, Do not use this product in heat, moisture,
flammable or explosive atmospheres.
3, Do not leave this product unattended while in use
to prevent accidents.
4, Please unplug the input power timely when not
using this product.

Product overview
The WM150 is a voltage and current power tester.
⚫Output PWM signal with an accuracy of 1
microsecond.
⚫Low voltage alarm. When the voltage is lower
than 6V and USB power is not supplied, it will
alarm.
⚫Real-time detection of voltage, current, power,
and displayed in curves or graphics.
⚫The device is simulated as a USB flash drive, and
the upgrade file is copied to implement product
firmware upgrade.

First start
1. Connect the power supply of 1-50V voltage to
the input port on the back of WM150. Need to
provide USB5V power supply, when the voltage
is lower than 6V. Otherwise it will alarm or not
boot.
2. The display shows the boot logo and stays for 2
seconds.
3. Boot sound with do-re-mid Simultaneously.
4. After the boot is completed, the display enters
the main interface as shown below:
5. If the position of the knob is not at the
minimum position, there will be a prompt
“Please pay attention to the knob position”
after booting, as shown below:

Main interface
After booting, the system counts into the main
interface, as shown below:
The dial on the left is a current display with an
accuracy of 10 mA and a maximum acquisition
current of 150 amps.
The middle histogram is the power display in
watts.
The 20.0ms and 1000us on the right side are the
period and pulse width of the output PWM signal.
The period cannot be changed, and the pulse width
is controlled by the knob.
The 11.2V on the right is the input voltage in
volts.
The 0mAh on the right is the capacity
accumulation. The unit will change with the size of
the capacity. Less than 1 ampere, the unit is mAh.
Otherwise it is ampere.

The lower right corner is the displayed working
time in seconds.
The grid below is a graphical representation of
the main port output current.
Other functions
Firmware upgrade:
After connecting the WM150 to the computer
with the USB cable in the box. the computer will
recognize the USB flash drive named Toolkit.
Download the upgrade file app.upg on the official
website to overwrite the files in the USB flash drive to
upgrade the firmware.
