Chapter 1 Overview
1, The instrument profile
VAT series is a multi-function meter based on 2.4G wireless data
transmission technology. It can measure miscellaneous parameters such as
voltage, current, power, charge and discharge capacity, watt-hour、time,and
temperatureand with over-current protection Protection, under-voltage
protection, and limited protection and other protection functions. The
instrument can automatically identify the direction of the current, and the
battery capacity can be monitored in real time, the instrument uses TFT LCD
display, display information is comprehensive, user-friendly and better
interaction.

Chapter II Instrument Description
1, Display instructions
1. The instrument is divided into two parts, including the display module and
measurement module, the display interface in both Chinese and English,
which can be set in the language settings.
Main display panel interface

2. The large font interface:
The main parameters such as voltage and current are displayed in the
large font interface for easy observation. After a few seconds, the main
interface will automatically jump to the large font display interface, and the
time can be set in the system settings. Reverse display interface easy to
observe in the light, please read the "Operating Instructions” for details.

power wiring diagram
The instrument can be "wired communication" and "wireless communication"
1. Display power supply wiring diagram is as follows:
When the display board is powered separately, there are two power
supply interfaces, which are the USB 5V power supply interface and the 2P
socket interface (8-16V) power supply.
2. Measurement module wiring diagram is as follows:
2.1, VAT1030 wiring diagram:
The wiring method on the left is applicable to the discharge measurement
of the battery and the measurement of the DC circuit; the wiring method on
the right is only applicable to the charge measurement of the battery.
Page 8
2.2, wiring diagram of VAT1050, VAT1100, VAT1200, VAT1300 measuring
voltage is 10-100V:
The above figure applies to VAT1050, VAT1100, VAT1200, VAT1300
measurement circuit voltage of 10-100V; attention at this time attention to the
jumper cap to receive 2W, the left wiring method is suitable for battery
discharge measurement and DC circuit measurement; The wiring method on
the right is only suitable for charging the battery.
2.3, VAT4300 measurement voltage is 0-400V and VAT1050, VAT1100,
VAT1200, VAT1300 measurement voltage is 0-100V wiring diagram:
The figure above applies to batteries or circuits where the VAT4300
measures 0-400V and VAT1050, VAT1100, VAT1200, and VAT1300 to 0-100V;
at this time, note that the jumper cap must be connected to 3W and need to
use a 10-30V. The DC voltage supplies power to the measurement module;
the wiring method on the left is suitable for the discharge measurement of the
battery and the measurement of the DC circuit; the wiring method on the right
is only suitable for the charge measurement of the battery.
Page 9
2.4, VAT1050, VAT1100, VAT1200, VAT1300 and VAT4300 external relay
wiring diagram;
The wiring method on the left is applicable to the discharge measurement
of the battery and the measurement of the DC circuit; the wiring method on
the right is only applicable to the charge measurement of the battery.
When selecting the relay, pay attention to the relay's contact can withstand
the maximum current in the circuit, such as the current in the test current is
80A, then select the relay, you must select the contact current can withstand
100A relay, the relay supply voltage can choose 12V or 24V When the 12V
relay is selected, the external power supply voltage must be set to 12V, which
is the same as the relay supply voltage.
