Great Planes Triton Charger - GPMM3150 - Manual (Page 15)

beforehand. Set the NiMH maximum charge input capacity, which ranges from 0 to
9900mAh. Setting a value of 9900mAh will effectively disable this feature.
9. TOP-OFF CHARGE: When fast charge has terminated the charger will supply
the selected amount of “top-off charge” current to help NiMH batteries achieve full
charge without overheating. Select the top-off charge rate, from 0 to 1000mA, which
should be approximately 7% of the fast charge current setting. For example, if fast
charge current is set at 2.5 amps, the top-off charge rate should be set at (2.5A x
0.07) 0.175A or 175mA. If fast charge is 1.0 amps, top-off charge rate should be set
at (1.0A x 0.07) 0.70A or 70mA. Triton will automatically terminate the top-off charge
after 20 minutes.
Triton stores various charge / discharge / cycle data which can be recalled for
viewing in the DATA VIEW MENU. This menu can be accessed from the MAIN MENU
by pressing the MENU and BATT TYPE buttons simultaneously. Or, this menu can
be accessed while Triton is performing a function by pressing only the BATT TYPE
button (pressing the MENU button returns the display back to the DATA VIEW
MENU). Rotate the dial to scroll through all screens in this menu. All data shown is
read-only and cannot be adjusted by the user.
“Input – Output:” The actual voltage being applied to the charger’s input will be
shown on the left, and the voltage measured at its output will be shown at right.
“Peak – Average:” The highest measured voltage or “peak voltage” recorded during
an entire charge period will be shown at left, and the average voltage calculated
during the entire charge period will be shown at right. Keeping track of both of these
measurements every time a battery is charged can help to evaluate its overall
condition as the battery ages. Typically, a battery’s peak and average voltage levels
will gradually decrease as the battery reaches the end of its usefulness.
“Chg/Dschg (01):” The amount of capacity delivered to the battery during any single
charge function will be shown at left, while the capacity delivered from the battery
during the discharge function will be shown at right (both measured in mAh). This
charger stores data for up to 10 cycles. Data for any particular cycle can be retrieved
by briefly pressing the dial, causing the cycle number in parentheses to blink. Rotate
the dial to select the actual cycle number which is to be displayed. Re-press the dial
to confirm the selection.
“Bat. Temperature:” This screen displays the actual temperature of the battery
under charge, measured in degrees Fahrenheit (F). An optional feature, it requires the
Triton Thermal Probe (GPMM3151) which is available separately. “No sensor” will be
displayed if the thermal probe is not connected.
