Feature: - 20A DC multifunction power meter - LCD display wih backlight, easy to read - Bult-in shunt design, no extra needed - Power, current, voltage and energy display and monitor timely , easy to know electric energy consumption - Electric energy clear function, perfect for various device monitor separately
- Overload alarm function (over power alarm threshold, the backlight and voltage flashing alarm) - Power memory, shave the power parameter when power down, safe to use
Operaqtion Tips:
1. The backlight control
By short press the button to turn on or off the backlight, In the bakclight mode,the data will automatically store when power down
2. The energy cleared
Step 1: Press the power button 5 seconds until the digital display "CLr" , then release the button;
Step 2: Now it is in the "energy clear" mode, press the button again, the energy data is cleared and stop flashing;
Step 3: If in the "energy clear" mode you do not press the button in 5 seconds,then the energy data will not be cleared
3. Set power alarm value
Step 1: Press the button, when the power area display "SET ", release button,
Step 2:it is in the pweor alarming setting mode, the voltage area displays the highest value of the voltage alarm,the current area displays the lowest value of the voltage alarm. Then you can press the button quickly to increase the value" +1", when there is no key operation more than three seconds,
It happens that this power meter may give incorrect readings (more than should be). It can be calibrated by opening up the back and shorting the pads marked "W" on the PCB, then add 20V to the input and 1A load (20 Ohms) to the output. Then power on, wait for the display say "Pass" then power off and remove the short. Ta-daa: calibrated.

I did a whole bunch of looking around for a supply monitor for my power supply I am building. This one seemed great but the minimum 6.5V input meant I could not supply lower voltages. Upon reading the reviews I found one detailing that removing the diode "D" and placing the power monitor supply positive lead on the cathode (part of the diode with the line on it). allowed for lower voltages to be measured. So I tried it and it worked! Just tweaked the alarm trigger to 0V and now it works great!

Hello, The load part of the device was short-circuited and the shunt resistance between the negative connections inside was burnt. Does any one know the value of this resistance?

Hey, hey,
The load part of the device was short-circuited and the shunt resistance between the internal negative connections burned. Does anyone know the value of this resistance?

hellocan you be more specific are you able to provide the R number or part number you are looking to replace, if that is not possible take a photograph of the damaged area and send it to me and I will see what I can do.as follow up if the parts you are refering to are R3

can i measure solar power with this i have 1 kva solar panels installed and connected to inverter
so i want to use this meter to connect inbetween solar and inverter to maesure current and voltage?

Hi Vaibhavkumar Birajdar, yes you could use this power meter. But be aware that you stay within it's parameters!...

Q:
In case someone don't know, this instrument can be calibrated for precise measurements. For this, you need a power supply set to 20V and a 20 Ohm resistor connected to the Load terminals. Use thick and short cabling. Remove the back cover, and find the two empty jumper holes in the corner opposite to the connector terminals marked "W". Temporarily short this, then connect the power supply. The display says "CAL" then "PASS", release the power. The instrument is now calibrated. Make a test measurement, correct the voltage if necessary (if after calibration meter shows more than should, raise calibration voltage, calibrate again)

Common positive, the current measuring shunt is between the negative lines.

This meter only measures up to 100V DC. You could theoretically use a voltage divider circuit to give only 1/3 of your voltage to the meter. It would only show a value up to 100V but you just need to multiply it by 3 to get your total voltage.
