Connections: The terminal marked "+" is for positive volts. The terminal marked "-" is for ground. These must be hooked up for the indicator to record battery usage. With only these two terminals hooked up, there will be no display showing. This is done to conserve battery power, but the meter is monitoring the batteries When you want to see the display, connect the terminal marked "C" to a positive volt source (+ and - terminals should still be connected). "C" can be hard wired to have the display showing all of the time or can be used through a momentary contact switch to see the battery status by depressing the momentary contact switch. Another method for installation would be to connect "C" to a terminal coming from a switch key that goes hot when the key is turned on. Remember that + and - must always be connected. Dimensions: Overall: Width 2 1/16" ; Height 1 1/4" Hole cutout - 1 3/8" wide by 7/8" high Depth Behind front meter flange to end of mounting screws - 1 1/8 inches
DC power is needed to power the meter.
DC positive and negative poles should be connected correctly!
Load and Shunt must be used for the meter to read Amps.
Shunt must be connnected between the Negative terminal and Load.

Product Description: 1--This round hour meter can be used for tracking time on machinery such as boats, cars, trucks, tractors or any other device where time is used to determine oil change intervals, service requirements or where there is a need to record hours operated. 2---These meters are 100% tested at the factory prior to shipment. They will have from 0.2 to 2.0 hours on them depending on the random quality control test selection process. This is done to insure that a quality meter is being shipped. 3---The timer has a 6 digit display with the least significant digit being 1/10 hour (99999.9) and operates on in put voltages from 6 to 80 Volts DC. 4---The hour meter timing mechanism contains a quartz oscillator which provides a high degree of accuracy. It is designed to withstand vibration and shaking up to 8g and is rated to work between 15 degrees to 132 degrees Farenheit. 5---The hour meter fits in to a 2" round hole and includes an adjustable retrainer clip so that the meter can be mounted on material up to 9/32 inch thick. Meter depth behind the panel is 1.5 inches.
Works for 36V battery, used for truck, RV, Golf cart or any battery operated unit
Temp range: -40F ~ 185F
Connection: Pin+: Battery+, Pin-: Battery-. C-signal output for external use
Only when the battery is properly charged then the 10th LED (far right) will be lighted.
As battery's state of charge decreases, successive LED lights up, only one at a time.
When 2nd (from left) LED flashes, indicating "energy reserve". When both 1st and 2nd LED flash,indicating "empty", new battery is needed to replace old one.
Battery indicator memorized the battery state is full when leaving factory. When use with a new battery, it should be powered on for at least 2 minutes to indicate the real battery state.
Range indication: Green: 41~100%, Yellow: 21~40%, Red: 20% less.
Forklift trucks, Golf Carts, RV's, Boats, Scooters and electric vehicle. etc.
