Introduction
The BAT-1 is a 2.25" instrument used to monitor your aircraft's battery power supply. It can be used on lead-acid, NiCad
batteries as well as gel cells. This instrument is very useful in determining your battery's health, charging status, as well
as the current load consumption of your aircraft. The BAT-1 can be used in both 12V and 24V aircraft and can measure
voltages up to 30V DC.
The BAT-1 uses standard current shunts and is able to measure currents in the range of 5A to 500A.The instrument
contains a programmable low/high voltage alarm to automatically detect bad batteries and alternator failures.

Page 2: Main Display
3 Main Display There are 3 main displays that can be setup to be displayed on the BAT-1: dual mode (current and voltage), voltage display only or current display only. The unit can be setup to toggle manually or automatically between voltage and current in the single value display modes. - Page 3 This display can be accessed by pressing the F1 key during normal operation. Pressing the F1 key again will reset the maximum values to the current voltage and current values. Pressing any other key will cause the BAT-1 to return to the normal display mode.

Page 4: Menu System
4 Menu System Pressing the rotary control button during the normal display mode will cause the BAT-1 to enter the menu system. Use the up/down keys or the rotary control to navigate through the menu system. If no key is pressed within 30 seconds, the BAT-1 will return to the normal display mode. -

Move the highlight over the “DONE” menu item and press the rotary button to return to the main menu Select the current capacity of your current shunt. The BAT-1 can use current shunts in the range of 5A to 500A. -
Page 6: Loading Factory Default Settings
5 Loading Factory default settings Pressing and holding the F1 and F2 keys simultaneously on power up will cause the BAT-1 to load preprogrammed factory default settings. The following screen will be displayed: 6 Operating the alarms If the alarm is activated, the corresponding item on the display will flash. - Page 7 7 Shunt selection The BAT-1 can use a current shunt in the range from 5A to 500A, 50mV to 100mV. Please note that the current shunt rating can effect resolution and accuracy of the BAT-1. Select a current shunt that is right for your application. Try use a current shunt that is close to the current range you are measuring.
- Page 8 10.1 Connection Diagram The use of an external 1A fuse is recommended. Connect the supply terminals to your aircrafts power supply. The BAT-1 can be used on both 12V and 24V without the use of any pre-regulators. Ensure that the supply voltage will not drop below 8V during operation as this may result in incorrect voltage and/or current readings.
- Page 9 BAT-1 Operating Manual Page 9 11 Warranty This product carries a warranty for a period of one year from date of purchase against faulty workmanship or defective materials, provided there is no evidence that the unit has been mishandled or misused. Warranty is limited to the replacement of faulty components and includes the cost of labour.
