3. Wire Selection
The 8005 and 8038 ammeters utilize an internal shunt as their current sensing device. The nature of current measurement is that the full current to be measured must fl ow through the sensing device. Therefore it is necessary to run wire to the meter of suffi cient size to carry the current to be measured. The wire size will vary depending on the total distance of the wire run, the TOTAL length of the positive and negative wires. There must be a fuse or circuit breaker in the positive wire lead to the meter. Choose a wire and fuse based on the table below.
Wire Run (Feet) 10 15 20 25 30 35 40 50 60 70 80 Wire Size (AWG) 10 10 8 6 6 6 4 4 2 2 2 Maximum Fuse (A)* 60 60 80 120 120 120 160 160 210 210 210
* These maximum allowable fuse sizes (Maximum allowable wire amperages) are for wires outside of engine spaces. Wires inside engine spaces have a maximum allowable wire amperage of 15% less, therefore maximum allowable fuse sizes must be reduced by 15%.
4. Connection
Notice the difference between a serial connection and a parallel connection in the diagram below. Internal shunt ammeters are mounted in a serial confi guration.
Choose the site in the circuit to be measured where the meter is to be installed. It may be either in the positive or negative side of the circuit. Break the circuit at this point and install the meter. Be certain to attach the wire end nearest the positive side of the circuit to the meter terminal marked + (positive). Attach the wire nearest the negative side of the circuit to the meter terminal marked - (negative)
5. Calibration
The 8005 and 8038 ammeters are calibrated at the factory and recalibration should never be necessary. However, if adjustment does become necessary the needle may be reset to the zero mark. In the center of the black area on the meter front is an adjustment screw. This screw activates a small cam that defl ects the meter needle slightly to adjust the needle position. Using a small screw driver, turn the screw no more than 90 degrees right or left, as necessary. DO NOT ROTATE THE ADJUSTMENT SCREW THROUGH 360 DEGREES.
