D. BATTERY CHARGER CONTROLS
NOTE: A buzz, or hum is normal when the output cables have
been disconnected and the AC power cord is still connected to
an electrical source (i.e. wall outlet).
Model PS-1022MA
Two switches permit Battery Type and Charge Rate selection.
Switch #1 (3 Modes)
Mode 1 – Manual Position: Use for charging in 2 Amp or 10 Amp
charge rates on 12 Volt batteries only. This charging must be
monitored and manually stopped when the battery is charged.
Overcharging will damage the battery.
Mode 2 – Automatic Position for Conventional Batteries. If you
are not sure of your battery type, use the (regular) conventional
setting.
Mode 3 – Automatic Position for Maintenance-free and Deep-
cycle batteries.
Switch #2 (2 Charge Rate Modes)
Mode 1 – Select the 2 Amp setting to charge small 12 Volt bat-
teries (31 Ah or less) or to warm larger lead-acid batteries.
Mode 2 – Select 10 Amp for larger 12 Volt batteries for a faster
charge.
Model PS-2100MA
Two switches permit Battery Type and Charge Rate selection.
Switch #1 permits selection of either regular battery in automatic
operation or Deep-cycle battery in automatic operation. If you
are not sure of your battery type, use the regular battery setting.
Switch #2 (4 Charge Rate Modes)
Mode 1 - Select 15 Amp, 6 Volt Manual Operation to charge
medium and large size wet-cell, lead-acid, 6 Volt batteries. Do
not charge small batteries such as used in motorcycles, lawn
and garden equipment. Note: Manual Operation. Monitor fre-
quently while charging a battery.
Mode 2 - Select the 2 Amp automatic setting to charge small
12 Volt batteries (31 Ah or less) or to warm larger lead-acid bat-
teries.
Mode 3 - Select 15 Amp automatic for larger 12 Volt batteries for
a faster charge.
Mode 4 - Select 100 Amp Engine Start to assist in engine crank-
ing of 12 Volt systems. DO NOT use on 6 Volt systems. Use the
100 Amp Engine Start position for cranking automobiles or light
trucks. Note: Use only with battery in the vehicle. This will re-
duce the chance of damaging sensitive electronic equipment in
the vehicle.

FULLY CHARGED BATTERY
Charge current to the battery is 0 Amp and,
the Full Chargegreen LED glows. The needle
points toward the Full Charge LED.
(Automatic Position)
E. READING METERS
APPROACHES FULL CHARGE
Charge current to the battery is
typically 5 Amp. The needle points
toward the 100% mark.
FULLY DISCHARGED BATTERY
Initial charge current to the battery is
typically 10 Amp. The needle points
toward the 25% mark.

AMMETER
The ammeter indicates the measured amount of amperes being
drawn by the battery. When you first start charging a battery, the
reading will be high with the needle near 10 using the 10 Amp
charge rate. As the battery charges, the needle will fall to about
4 to 5 Amps, indicating a charged battery in the manual setting.
In automatic setting, when the battery is charged, the ammeter
will go to zero and then will pulse frequently to monitor the bat-
tery. At the 2 Amp charging rate, you will see little needle move-
ment.
The percent of charge scale is intended as a visual aid to help
simplify reading the state of charge of the battery. The meter is
scaled for use with the 10 Amp charge rate only. For the 2 Amp
charge rate use the red triangle. The percent of charge is based
on current drawn by the battery. For this reason accuracy will
vary with size and battery type.
