an operational reference - Refer to the
manufacturer’s battery manual and/or CMM for
battery specific information
MasterCharger Tutorial 2

Warnings (specific)
1. Observe precautions when handling batteries
1. Batteries are heavy
2. Batteries will generate extremely high currents if shorted
•Tools can easily be dropped shorting several cells
2. Follow battery test procedures as outlined in the
CMMs and OMMs provided by the manufacturers.
3. The Operator is ultimately responsible for the
correct and proper analysis of the batteries under
test.

Receiving –Inspection
Unpacking the unit
1. Caution! Heavy equipment.
2. Verify that the following are in the package:
•Charger-Analyzer
•Accessory Kit containing:
•Battery Cable
•Temp-Plate
•Single Cell Adaptor
•Spare Parts

Installation
1. Place the Charger-Analyzer on a suitably strong bench
1. Caution! Heavy equipment (175 lb. –79.3 Kg)
2. Connect to a dedicated (not shared) outlet with
208V/230V/240V with 30A capability (with motor load
rated circuit breaker)
1. In the US, use a NEMA-630R receptacle
2. Verify that the unit is wired for the proper line
(mains) voltage (see manual for wiring diagrams)

Installation (continued)
2. Connect the Battery Cable to the Front Panel and connect
the Temp-Plate sensing pig tail cable to the temp-plate
•Note that there are two DB9 cables in the Temp-Plate.
Connect to either one (the other one is used by the
BTAS-16)
6MasterCharger Tutorial

Installation (continued)
3. Turn Power ON
4. Observe the following:
•Meters and Timer indicators are ON
•Ammeter reads zero and Voltmeter reads about 0.2V
•Status indicators show RESET (green)
5. Place a battery on the Temp-plate
6. Connect a battery to battery cable and note that the
Voltmeter now reads the battery voltage.

10MasterCharger Tutorial

Basic Information
1. The MasterCharger Battery Charger-Analyzer operates based
on settings indicated by knobs and switches on the front
panel of the MasterCharger
2. Unit operation is based on the following parameters:
•Main Charge Current Selector
•Topping Discharge Current Selector
•Main Time Selector Switch
•Total Time Selector Switch
•Keypad
•Cell Selector
•Voltage Mode Selector
3. Consult the CMMs for battery specific test parameters when
setting up the charger/analyzer for test.
11MasterCharger Tutorial

Current Selectors
1. Both Main Charge and Topping/Discharge Current Selectors
are ten turn potentiometers with numeric read out displays.
2. Dial 10 for 1 Amp, 20 for 2 Amps, 50 for 5 amps, 500 for 50
amps, etc.
3. Maximum current for charging is 50 Amps
4. Maximum current for discharge is 60 Amps (older units 50
Amps).
12MasterCharger Tutorial

Main and Total Time Selectors
1. Set the amount of time the unit is in the main portion of the
charge and the total amount of time the unit is in charge.
2. The total time also controls the amount of time that the unit
is in topping charge and discharge modes, independent of
the main time setting.
3. Lines on keypad indicate which settings apply to which tests.
4. e.g. Set Main to two and total to six for a standard full charge
six operation.
13MasterCharger Tutorial

Keypad Functions
1. Green: Stop/reset, cycle end
2. White: Two rate charge mode (main and topping)
3. Yellow: Single Rate charge mode
4. Blue: Auto cut-off discharge (analysis).
5. Red: Full discharge (deep cycle).
6. Note associated Indicators
14MasterCharger Tutorial

Status Indicators
1. RESET: unit is in standby
2. CYC END: unit has completed cycle
3. DUAL: Indicates that DUAL rate mode is selected
4. MAIN: Indicates that the unit is in MAIN charge
5. SINGLE: Indicates that the SINGLE rate mode is selected
6. TOP: Indicates that the unit is in TOPPING charge
7. AUTO: Indicates that the AUTO mode is selected
8. DISCH: Indicates that the unit is in AUTO discharge
9. CAP FAIL: Indicates that the battery has failed capacity
10. OPEN LIM: Charge or discharge limiter is open
11. OVER TEMP: Continuous = no temp-plate, flashing means over
heat of battery
12. VOLT FLT: Continuous = reverse polarity detected, flashing means
battery voltage to high for cell settings.
13. CURR FLT: Current not within 1 Amp of set current
15MasterCharger Tutorial

Cell Selector and Voltage Mode Selector
1. Cell Selector adjusts the unit to operate for test on NiCds of
various cell numbers.
2. Is also used to set the charger up for use with SLA batteries of
various voltages (see the manual).
3. Voltage Mode Selector adjusts the type of charge operation to the
unit is setup to perform
4. Options are Constant Current, Constant Voltage, Peak Transfer
(newer units) and Peak Stop
