This section gives an overview of how to quickly get started capacity discharge testing a battery using your Beta D-50. If there is uncertainty at any point on how to proceed, please refer to the more detailed instructions in the section 4. - Page 9 LED and “OP” on timer is off.) without the cutoff voltage being reached. The battery is usually fit for service, after complete recharge. See below under respective battery type. BETA D-50 TESTER / ANALYZER - OPERATING MANUAL V2.2 Page 7...
- Page 10 NOTE: If in emergency it is required to stop the test, switch the unit to off/reset. When the test is restarted the timer is reset to zero. It may be necessary to recharge the battery before resuming the test. BETA D-50 TESTER / ANALYZER - OPERATING MANUAL V2.2 Page 8...

Page 11: Detailed Operating Instructions
With increasing hours of use or age, the battery capacity decreases. Therefore, battery manufacturers usually recommend testing for a capacity equal to 80% of the original ampere-hour rating.

- Page 13 A schematic of the circuit diagram for the Beta D-50 can be seen in figure 4-3. At the end of discharge, the calculation of ampere-hour capacity is the product of discharge current and the elapsed discharge time.
- Page 14 4.4 DISCHARGE TIME 4.4.1 TIMER UNIT SETTING The Beta D-50 has a built in timer, allowing discharge time settings from 0 minutes to 999.9 minutes. Page 12 BETA D-50 TESTER / ANALYZER - OPERATING MANUAL V2.2...
- Page 15 To determine the full capacity of the battery a longer time can be set (several hours). The Beta D-50 will then continue the discharge test only until the cutoff voltage has been reached. The timer, cutoff voltage and discharge current displays will freeze at this point.
- Page 16 Table 4-3. Discharge test setting for nickel-cadmium batteries 4.5.3 SETTING CUTOFF VOLTAGE ON THE BETA D-50 Before setting the cutoff voltage, a battery has to be connected and the unit has to be turned on. Page 14 BETA D-50 TESTER / ANALYZER - OPERATING MANUAL V2.2...
- Page 17 For example, a SLAB battery with a 30 ampere-hour 1-hour capacity rating would be tested with the discharge current set to 24 amperes. Before setting the discharge current the Beta D-50 must have been connected to the battery (see section 4.5) and the AC power switch must have been turned on.
- Page 18 4.7 TEST COMPLETION AND ANALYSIS The Beta D-50 automatically completes the test with the set parameters. It may however be required to measure the individual cell voltages for nickel-cadmium batteries during the test (see section 4.7.2).
- Page 19 Refer to the battery manufacturer's maintenance manual on how to proceed. 4.7.1 LEAD-ACID BATTERY If the lead-acid battery has been accepted by the Beta D-50 discharge test it has successfully completed the capacity test. 4.7.2 NICKEL-CADMIUM BATTERY Check each cell with a digital voltmeter near the end of the test.

Page 20: Calibration And Maintenance
There are two main indicators that can be periodically calibrated: 1) the voltmeter; and 2) the ammeter (see figure 1-1 in section 1). The Beta D-50 is equipped with two sets of test jacks for easy calibration of these digital display meters. In addition the internal shunt, even though calibrated and certified by the shunt manufacturer, could be verified. - Page 21 DC voltage range appropriate for the connected battery. SWITCH ON MAINS POWER Turn on the AC on-off/reset power switch. An audible alarm sounds, and the Accept lamp illuminates. Meters read all 6's or 8's.

- Page 23 The millivolt meter will read the millivolts dropped across the Beta D-50 internal shunt when a discharge current is drawn. The circuit diagram for the calibration can be seen in figure 5-2.
- Page 24 Repeatedly turn the Current Adjust knob fully counter-clockwise to set discharge current to zero. CONNECT BATTERY Connect the battery DC cable to the battery and ensure the connector is plugged in completely. Page 22 BETA D-50 TESTER / ANALYZER - OPERATING MANUAL V2.2...
- Page 25 SET DISCHARGE CURRENT Turn the Ampere Adjust knob clockwise to the rated ampere-hours, i.e. 40 amperes for 40 ampere-hour battery. The ammeter displays the current as it is being adjusted. Page 23 BETA D-50 TESTER / ANALYZER - OPERATING MANUAL V2.2...
- Page 26 To verify the accuracy over the range of the meter, additional current settings could be checked. Since the Beta D-50 digital meters are linear, checking two or three current settings are adequate to verify the range. The easiest way to check additional current settings is to repeat steps I and J but setting a lower discharge current in step I.

Page 27: Shunt Verification
5. CALIBRATION AND MAINTENANCE 5.4 SHUNT VERIFICATION The Beta D-50 internal shunt is calibrated and certified by the shunt manufacturer. The shunt is a linear resistive device consisting of a heavy brass base and heavy manganin (copper alloy) resistance. It is not necessary to calibrate the shunt, however the shunt could be verified with the help of an external calibrated shunt and a millivolt meter (see figure 5-3). - Page 28 5) Check all leads for tightness 5.5.3 REPLACEMENT OF FUSES The Beta D-50 is equipped with two fuses. One 3 ampere AC line fuse and one 70 ampere DC line fuse. See specification in section 7 for the specific types of fuses required.

The open circuit voltage of a fully charged cell is about 1.35 volts. The discharge voltage is about 1.2 to 1.1 volts and varies with temperature, discharge rate, charge state, and age.

For example, a 24-volt battery rated at 30.0 ampere-hours should deliver 30.0 amperes for a minimum of 1.0 hours before reaching the 18.0 volts cutoff voltage. This is a one-hour, C -rate discharge.
