Running DiagnosticsFigure 44. A/D DiagnosticsCount, Voltage, Error Count, Start and Stop - To start the test, click Start. The Count andVoltage boxes display the A/D count and voltage. If the A/D count varies outside the rangedetermined by the A/D Threshold Deviation value, an error is recorded in the Error Count box.To stop the test, click Stop.12.2 Load Bank DiagnosticLoad bank diagnostics may be used in two ways. Click a single step On to display the loadcurrent, battery voltage, and step resistance; or perform a cumulative resistance test, whichsaves the individual step resistance to the setup file.If the user do not enable Auto Detect Step Resistance (refer to Load Bank), the user must enterthe resistance for each step. There are two methods to obtain this information, and acombination of the two may be necessary. After resistance values are entered, the data issaved with the load bank setup information for the currently selected load bank.4200-020R2.0 38 9/25/2009
Table of FiguresFigure 45. Load Bank DiagnosticsThe first method to obtain the step resistance is to use an ohmmeter to measure the resistanceof the steps.WARNING:Be sure that power is removed from the load bank before measuring resistance valueswith an ohmmeter.The user may use an ohmmeter to measure the lower steps that have a higher resistance but,to get accurate readings, the user should use a micro-ohmmeter to measure the upper stepsthat have lower resistance values of 20 ohms or less.The user may also use the MLC program to obtain step resistance values. To set up the loadbank resistance, first select a Start Step in the Resistance Test group. Depending on shuntrating, selecting Start Step 3 or 4 is recommended, because lower steps produce very lowvoltages across the shunts, which may result in inaccurate readings.Select a Stop Step in the Resistance Test group. Ensure there is sufficient current to drive thestop step selected.Verify the Battery Voltage box displays battery or charger voltage. If the voltage is not displayed,fix the electrical connections before continuing with the test.To begin the load bank resistance test, click Start. The graph fills with resistance values.Observe the bottom axis of the graph. Plots on the graph alternately indicate the resistance ofan individual step and the cumulative (parallel) resistance of the steps up to that step. Doubleclickthe graph to maximize it.4200-020R2.0 39 9/25/2009
