0.28 small Bule digital voltmeter 2 wires DC2.40-3

 0.28 small Blue digital voltmeter 2 wires DC2.40-30 Bule 

功能简介

1.量程：2.4-30V(红色） 2.6-30V（黄）2.6-30V(绿） 3.2-30V(蓝）

2.配有两根导线，接线方便简单，方便接入汽车/电瓶车/摩托车车内线路

3.具有反接保护功能，线接反不会烧毁，本产品具有微调功能

4.注意使用最高输入电压不能超过30V.否则有烧毁的危险

5.在电压低于3.0V时，显示亮度会变暗，但不影响正常测量。

6.在测量10V以下电压时，小数点后显示两位；在测量10V以上电压时，小数点后显示一位。既能照顾到电池用户的对测量精度的需要，又能照顾到测量更高电压的需要。

Introduction to features

1. Range: 2.4-30V (red) 2.6-30V (yellow) 2.6-30V (green) 3.2-30V (blue)

2. With two wires, wiring is simple and easy to access the car / battery car / motorcycle car line

3. With reverse protection function, the line will not burn back, this product has fine-tuning function

4. Note that the maximum input voltage can not exceed 30 V. Otherwise, there is a risk of burning

5. When the voltage is lower than 3.0V, the display brightness will darken, but does not affect the normal measurement.

6. When measuring the voltage below 10V, two digits are displayed after the decimal point. When measuring the voltage above 10V, one digit is displayed after the decimal point. Both to take care of the battery user's need for measurement accuracy, but also to take into account the need to measure higher voltage.
