Specifications:Work Current:5-15mA (with backlight)Work Voltage:6-12VEnergy Resolution:1%Voltmeter Accuracy :1%Using Temperature Range: -20- 70degreesOperating humidity:10-80%(non-condensing)Black wire connect negative electrodeRed wire connect positiveExternal dimension:482921 mmHole Dimensions :45.526.5 mmHow to Use:1. Pull the white button on the backside for about 3s until it shows 1-U and release it. Pull it again for 1s it shows 2-b and release it. Pull it again for another 1s it shows 3-c and release it. Pull it again for another 1s it shows 4-d.2. When it shows 1-U, pull the white button for 3s then you can adjust the voltage admeasuring apparatus. Pull it for a longer time, the voltage goes up. Then pull it for another longer time, the voltage goes down. Do it again and again. To save and exit Automatically after the screen is twinkling.3. When it shows 2-b, you can change the type of battery.12V: 1pc 12V Lead-acid battery3.7V: 1pc 3.7V Lithium polymer battery3.2V: 1pc 3.2V Lithium iron phosphate battery1.2V: 1pc 1.2V NiMH battery4.When it shows 3-c, you can adjust the number of batteriesPlease refer to the following:12V Lead-acid battery: 1-8pcs3.7V Lithium polymer battery: 2-28pcs3.2V Lithium iron phosphate battery: 3-32pcs1.2V NiMH battery: 10-70pcs5.
