一、Overview
FNB28 USB tester is a high-reliability, high-safety USB voltage and current detection meter
and mobile communication terminal fast charge trigger. With 0.96 inch TFT LCD display. Can be
used to measure the power supply or power consumption of products such as USB interfaces,
mobile phone chargers, U disks, etc .; can be used to measure mobile phone charging power, mobile
power input and output conditions; can be used to test the fast charging protocol of chargers.
This instruction manual includes relevant safety information, warning tips and solutions to
common abnormal conditions, please read the relevant content carefully and strictly observe all
warnings and precautions.
二、Pay attention to safety matters
1、Do not connect a power supply exceeding 24V to the tester.
2、FNB28 supports high power input (such as 20V * 5A = 100W).
3、When using high voltage and high power work, the temperature of the tester will rise.
Please be careful to prevent burns.

Figure 2
Description
Only the four key parameters of voltage, current, power, and load equivalent impedance are
displayed. This page can change the display direction.
Instructions
(1) K1 key
Short press: Turn the page.
(2) K2 key
Short press: Turn the page.
Long press: switch screen display direction.
2、 Capacity / power consumption observation page (see Figure 3)
Figure 3
Description
FNB28 supports 4 sets of capacity / power consumption records.
XXX: XX: XX (white) indicates the capacity and power consumption recording time,
corresponding to 4 groups of capacity and power consumption, each has a recording time, and it
will not be lost when the power is off.
XXX: XX: XX (magenta) indicates the running time after power on, and reset after power on.
→Represents the direction of current.
Instructions

(1) K1 key
Short press: When set to manual recording, recording can be paused / started, and it is invalid
when set to automatic recording;
Long press: Clear the current group record data, including capacity, power consumption, and
record valid time;
(2) K2 key
Short press: page turning;
Long press: Switch to the histogram page (see Figure 4)
3、 Histogram page (see Figure 4)
Figure 4
Description
The capacity and power are expressed in two colors. The unit is shown below. The
measurement length is 65 units. The calculation formula is as follows:
Capacity: Red: x, unit: 2000mAh
Yellow: y, unit: 2000/65 = 30.76mAh
Capacity = 2000 * x + 30.76 * y (mAh)
Power: Blue: x, unit: 200Wh
Green: y, unit: 200/65 = 3.07Wh
Power = 200 * x + 3.07 * y (Wh)
Instructions
