Ammeter
The Ammeter indicates the amount of current, measured in amps, that is being drawn
by the battery. As a battery takes on a charge, it draws less current from the charger.
Correspondingly, the meter will show less current being drawn by the battery. When the
current stops decreasing, the battery is charged. The 2 amp charge rate may indicate some
activity on the meter, although the meter does not have the resolution to display this low rate.
Voltmeter
The voltmeter indicates the voltage at the battery terminals. The charger need not be
plugged into an AC outlet. The timer should be in the OFF position. Then connect the
charger following the instructions in sections 6 and 7. Observe the meter indication.
Keep in mind that this reading is only a battery voltage reading, a false surface
charge may mislead you. We suggest that you turn on the headlights for a couple of
minutes before you read the meter. Read it a couple of minutes after you have shut
the headlights off. If the reading is less than 10.5-volts, the battery may be bad or the
connection at the charger may be poor. If the reading is 10.5-volts to 12.8-volts, the
battery is low – recharge it. If the reading is above 12.8-volts, the battery is charged.
Charge Rate Selector Switch
Use the Charge Rate selector switch to select the charge rate or engine starting setting
you require.
1.5A, 2A, 4A and 5A Slow Charge Rate• – Intended for charging small batteries such
as those commonly used in garden tractors, snowmobiles and motorcycles.
10A, 20A, 30A and 35A Fast and 40A, 60A, 65A and 80A Rapid Charge Rate• –
Use for charging automotive, marine and deep-cycle batteries. Not intended for
industrial applications.
125A, 180A, 200A, 225A, 250A and 300A Engine Start• – Provides high amperage
for cranking an engine with a weak or run down battery. Always use in combination
with a battery.
Model PSW-2035 employs 2 toggle switches:
Switch #1• – Use this switch to select the 200 Amp Engine Start and the 35 Amp
Charge Rate. Switch #2 must be in the down position (Select Position) when using
Switch #1.
Switch #2 – Use this switch to select the 2 amp Charge Rate and the OFF position. •
Also, use to select use of Switch #1. Note that Switch #1 is only effective when
Switch #2 is set to “Select Position.”
Model PSW-61224 employs a 7-position rotary switch.
You may select the output voltages of 6, 12, or 24 volts for charging the batteries of •
those voltages or battery combinations connected in series (not parallel) in which
the sum of the battery voltages adds up to the range selected. Each voltage range
offers a high or low amp charge rate. The higher charge rate is more suitable for fast
charging a battery to the point where it will start a vehicle, the lower (slower) charge
rate is more suitable for fully charging (restoring) a battery. (See the Input/Output
Chart on the Battery Charger.)
Voltage Selector Switch
Use this switch to set the scale of the voltmeter to either 6 volt and 12 volt DC to match
the battery or batteries being charged. NOTE: This does not change the output voltage
of the charger.
Battery Load Tester Switch (Model PSW-3060 only)
Use this switch to apply a load to the battery when testing it. (See Using the Battery
Load Tester Feature section.)
OPERATING INSTRUCTIONS12.
Charging (Model PSW-2035)
Ensure that all of the charger components are in place and in good working 1.
condition, including the plastic boots on the battery clips. Make sure the electrolyte
(battery liquid) in each cell is at the correct level.
Set the charge rate selector switch (switch #2) to the OFF position.2.
Connect the battery following the precautions listed in Sections 6 and 7.3.
Connect the AC power following the precautions listed in Section 8.4.
Place the charge rate selector switches (switch #1 and #2) in the preferred position.5.
