To adjust the discharge cut-off voltage refer to the parameter settings listed above. To change the values of the cut-off short press the Cell button to decrease the value, to increase the value short press the MODE button. To start the discharge process press the MODE / DISCHARGE button for at least 1 second and “discharge” will ﬂash on the screen once startup has begun. The iChecker v.3 will slowly toggle showing each individual cell’s voltage or short press the CELL button to toggle through each cell’s voltage individually. Once the battery is discharged the iChecker v.3 will sound a constant double beep sound. WARNING: Do not a leave Lithium battery connected to the iChecker v.3 after the battery has discharged. The iChecker will continue to use the battery’s power to stay powered up using the batteries power, irregular balance and damage to the battery could happen. On startup if a single cells voltage is lower than the cut-off adjustment the iChecker will not go into discharge mode and will be indicated by double beep sound error. 4.20 V 99% Short Press CELL Button to show individual cell voltage and remaining capacity Lowest Cell Voltage Shows the lowest cell number, voltage and remaining capacity Total Voltage (%) 2S iChecker v.3 Li-Ion Li-Po Li-Fe Li-Hv NiCd NiMH 6S MODE MODE 87654321 Lithium 30 87654321 Servo 5V Power IN NiCd/MH Lithium LE Li-Ion Li-Po Li-Fe Li-Hv NiCd NiMH PPM Adjust TYPE Setup Menu PPM Adjust PPM Adjust H 87654321 s 5S 8.40 Discharge Sound Switch Setting Servo 5V Power IN NiCd/MH iChecker v.3 Servo Test PPM OUT iChecker v.3 Servo Test PPM OUT LCD Backlight Operating Time Setting Servo Test PPM OUT Servo Test Signal Range Setting 2500 4S 3.52 Discharge cut-off voltage range: 2.0-4.2v/cell Servo test frequency setting: 50Hz, 60Hz, 100Hz, 200Hz, 300Hz Li-Ion Li-Po Li-Fe Li-Hv NiCd NiMH 3S 2S Servo 5V Power IN NiCd/MH 3.700 PPM Adjust Setup Menu CELL PPM Adjust PPM Adjust TYPE 8S Total 2S MODE Lithium 7S V Servo 5V Power IN NiCd/MH 6S Lithium 5S Lithium 4S 87654321 3S iChecker v.3 Servo Test PPM OUT 2S 30.80 Servo Test Range Setting 1S Discharge Cut-Off Settings Servo Test Freq.

Display (Default Mode) Type Connect battery to power up iChecker v.3 The iChecker v.3 has a built in smart detection to tell the difference between all lithium cell types. Depending on the battery’s voltage the battery type could be incorrect, short press the TYPE button to toggle through the types. Choose the correct type to view the remaining capacity % correctly. Max-Min V MODE Highest Cell Voltage Shows the highest cell number, voltage and remaining capacity Lowest and Highest Cell Difference Highest/lowest cell voltage display showing voltage gap Nickle Battery Testing Connect battery to power up iChecker v.3 Upon start up the iChecker v.3 will display the battery total voltage, cell count and remaining capacity. Depending on the battery voltage the cell count could be less than what is displayed. Press the CELL button to choose the correct amount of cells the battery has, the remaining capacity % will be correctly displayed. The iChecker v.3 cannot display individual cell voltage for mulitple nickle cell batteries. Servo Testing Connect 5-6v battery to the power in port to power up iChecker v.3 Upon start up the iChecker v.3 will display the voltage of the battery to supply power to the servo. Plug servo into the servo test ppm out port located on the left side of the iChecker. To start servo testing hold the CELL (servo test) button for at least 1 second. Move the PPM dial located on the left side of the iChecker to manually operate the servo, short press the CELL button to center the servo. Press the MODE button to start auto servo movement, to adjust the servo speed move the PPM dial. ESC Testing Connect the esc signal line to the PPM port located on the left side of the iChecker. A power source is needed to power your esc. Plug the battery into the esc and the iChecker will power up. The function for the esc is the same as the servo testing. Please note that it is not recommended that a motor be connected to the esc for testing as it will cause your model’s motor to run.
