Peak Charge Volts Display Mode; Discharge Mode; Discharge Average Voltage Display; Relative Internal Cell Resistance Display - Competition Electronics TURBO30 TURBOFLEX Operating Instructions Manual

The charge mode has a peak detect drop-back voltage warning built into it. If the peak detect drop-back voltage
exceeds .03 volt for a dingle cell or .09 for a multiple cell pack, the warning message 'PEAK DET TOO HI-BAT
MAY NOT PEAK' will appear. If you still desire to continue, just press the (START) push button again.
Otherwise, push the (UP ARROW/OFF) or the (LEFT ARROW) push button to go directly to the screen needed to
change the value. We recommend a value of .03 volts for a single cell and .05 volts for packs. Generally, the larger
the value the hotter the battery will become at the end of the charge. Any value over .03 volts for a single cell may
cause the cell not to peak. A high value of charge current will also give hotter batteries.
The standard peak detect lockout time is 60 seconds. This means the charge will run 60 seconds even if the battery
voltage is dropping. A long peak detect lockout of 10 minutes can be selected in the default menu. The long
lockout will only last one charge and must be reselected if needs again. It will also be cleared if the (UP
ARROW/OFF) button is pushed. The long peak detect lockout is meant to be used with packs that have a bad
tendency to false peak.

PEAK CHARGE VOLTS DISPLAY MODE

To display the peak charge volts, push the (LEFT ARROW) button until you see the message 'PEAK CHG V
XX.XX'. The 'XX.XX' digits show the supply volts. It is useful to detect a nearly dead automobile battery or a
supply that is past the maximum of 18 volts allowable under the warranty. The supply volts are also displayed while
running main modes of operation. This is useful for detecting a weak supply during charging.

DISCHARGE MODE

To run the discharge mode, push the (DISCHRG) button. You may also push the (LEFT ARROW) button until you
see the message 'DISCHG AMP XX XC'. The letters 'DISCHG' mean you are in the discharge mode. The 'XX'
digits show the discharge rate selected in amps. Maximum discharge rate for 1,4 and 6 cell is 30 amps or 25 amps
for 7 cells. Minimum setting is 5 amps. The 'XC' indicates the number of cells to be discharged. Set the amps and
number of cells by using the (LEFT ARROW) button and the (UP ARROW/OFF) button. The cutoff volts for 1, 4,
6 and 7 cell packs can be set in the DEFAULT MENU. To get there, just press the (MENU CHNG) push button.
Press the (MENU CHNG) push button again to get back.
To run the discharge mode, you must have the 'DISCHG AMP XX XC' message on the display and the voltage ON
THE DISPLAY must be above the cutoff voltage and below a maximum of 1.5 volts per cell. You may have to wait
a few seconds for the voltage to come up when connecting up a pack before you can push the (START) button.
When you push the (START) button, the message 'DISCHGING XX.XX' will appear to indicate that you are
actually discharging.. The 'XX.XX' digits show the supply volts. The actual discharge time in seconds, the pack
volts and the discharge current will be displayed on the top line of the display and are updated constantly.
After your pack has reached the drop-out voltage, the message 'DISCHARGE DONE' will be displayed. To get to
the 'DISCHG AMP XX XC' display, push either the (LEFT ARROW) or the set digit (UP ARROW/OFF) button.
The discharge time for the pack is displayed in the upper left hand corner. The discharge time is useful to check the
amount of time left tin your pack to determine gear sizes. A 20 amp discharge rate is useful to get approximate run
time left for 1/0 scale cars.

DISCHARGE AVERAGE VOLTAGE DISPLAY

After the discharge or cycle mode has been run, the average voltage of the pack or cell during discharge can be
displayed. Just push the (LEFT ARROW) button until the message 'DISCHG AVE X.XX' is displayed.

RELATIVE INTERNAL CELL RESISTANCE DISPLAY

After the cycle mode has been run, the relative internal resistance of the cell can be displayed. Just push the (LEFT
ARROW) button until the message 'INTERNAL RES XX' is displayed. The lower the relative internal resistance
the more punch the cell will deliver. Another effect the oval racers find is that the lower resistance SCRC packs
have more speed at the end of the run. The RED SCR's and the BLACK SCRC's will have a range from 25 to 40
for a single cell. The PURPLE P-170's will have a range from 35 to 75.
