3-3. Charge Function Check

Note1: When perform this check, don’t apply a voltage to battery terminals.

Note2: Be sure to disconnect the AC adapter when connecting the resistors. Doing so with the power supply connected causes a trouble.

3-3-1. Voltage adjustment and checks

Procedure:

1.Connect the digital multi meter to battery terminals.

2.Connect the AC adapter to the set.

3.Enter the test mode (Display Check mode).

4.Press the [VOL+] key to enter the Manual mode.

5.Press the [VOL+] key twice, press the > key once, press the [VOL+] key once, press the > key once, press the [VOL+] key three times to display as follows.

7. Adjust with [VOL+]/[VOL--]keys so that the value of digital multi meter becomes 1.80 ± 0.01V.

8. Press the X key on the set or key on the remote commander to write the adjusted value.

9.Press the > key to select the item number 2262.

10.Confirm that the value of digital multi meter is 1.20 ± 0.024V.

11.Press the > key to select the item number 2263.

12.Confirm that the value of digital multi meter is 2.17 ± 0.05V.

13.Press the x key four times and back to the Display Check mode.

3-3-2. Ampere checks

Procedure:

1.Connect the 22 ohms resistor (more than 0.1 watts) and ampere meter to battery terminals.

2.Connect the AC adapter to the set.

3.Enter the test mode (Display Check mode).

4.Press the [VOL+] key to enter the Manual mode.

5.Press the [VOL+] key twice, press the > key once, press the [VOL+] key once, press the > key once, press the [VOL+] key three times, press the > key four times to select the item number 2264.

6.Confirm that the value of ampere meter becomes specification value. (Refer to “table 3-3-1. Ampere Specifications”)

7.Press the x key four times and back to the Display Check mode.

8.Cut the power supply and remove the resistor that connected to the battery terminals.

9.Repeat checks to item number 2267 at the same manner as step 1 to step 8. ( Refer to “table 3-3-1. Ampere Specifications” for the kind of the resistor that connected to the battery terminals at step 1)

3-5. Setting The Adjustment Values

3-5-1. Hi-MD3 setting

Preparation:

1.Perform calculation every item based on the data given by the Hi-MD3 adjustment disc by referring to the following table. (Round off the value in decimal place)

2.Convert the calculated value into hexadecimal number.

Note: The Hi-MD3 adjustment parameters vary depending on the disc, and therefore use the parameters of the disc used when performing the adjustment.
