■ Calibrating the Generation Feature

Operation procedure:

<1> Warm up the standard.
<2> Before turning on the power of the CA11E calibrator, connect it to the standard.
<3> Turn on the power of the instrument.
<4> Simultaneously press and hold the [▲1] and [▼4] keys (shown in the figure in the “Assign-

ment of Keys for Calibration” section below) for about 2 seconds to enter the calibration
mode.

<5> Select the generation range to calibrate using the MEASURE/SOURCE selection switch

and range selection rotary switch. The display unit shows “CAL,” “SOURCE,” “ON,” “0,” and
the lower limit.

<6> Read the output value of the CA11E using the standard (digital multimeter), and using the

[▲] and [▼] adjustment keys adjust the CA11E so that the output value is set to the offset
value. Then press the [▼1] input determination (ENTER) key to fix the setting.
After fixing the setting, the display unit reading changes to “CAL,” “SOURCE,” “ON,” “FS,”
and a full scale of the range.

<7> Read the output value of the CA11E using the standard (digital multimeter), and using the

[▲] and [▼] adjustment keys adjust the CA11E so that the output value is set to the full
scale value. Then press and hold the [▼1] input determination (ENTER) key for about 1
second to fix the setting.
After fixing the setting, the display unit shows “0 FS” blinking. Re-press and hold the [▼1]
input determination (ENTER) key for about 1 second to write the calibration coefficients to
the EEPROM of the instrument. (This overwrites the previous calibration coefficients.)
When this is complete, the instrument returns to the status in Step 5.

<8> Repeat Steps 5 to 7 for each range to be calibrated.

■ Calibrating the Measurement Feature

Operation procedure:

<1> Warm up the standard.
<2> Before turning on the power of the CA11E calibrator, connect it to the standard.
<3> Turn on the power of the instrument.
<4> Simultaneously press and hold the [▲1] and [▼4] keys (shown in the figure in the “Assign-

ment of Keys for Calibration” section below) for about 2 seconds to enter the calibration
mode.

<5> Select the measurement range to calibrate using the MEASURE/SOURCE selection switch

and range selection rotary switch.
"CAL” and “MEASURE” appear and “FS” blinks on the display unit.
(If a value nearly equivalent to full scale has been input, a measured value and “FS”
appear.)

<6> Set up the standard in order to input the full scale value to the instrument. Wait until the

reading stabilizes, then press and hold the [▼1] input determination (ENTER) key for about
1 second to fix the setting.

<7> After fixing the setting, “0” and “FS” indications on the display unit start blinking. Re-press

and hold the [▼1] input determination (ENTER) key for about 1 second to write the calibra­tion coefficients to the EEPROM of the instrument. (This overwrites the previous calibration
coefficients.)

<8> Repeat Steps 5 to 7 for each range to be calibrated.

To return to the previous step:

<9> To return to the previous step without fixing the setting, press the [▲1] input cancellation

key. Note that this is possible only before writing to the EEPROM.

To return to the normal operation mode:

<10>Simultaneously press and hold the [▲1] and [▼4] keys (shown in the figure in the “Assign-

ment of Keys for Calibration” section below) for about 2 seconds, or press the [POWER] key
to turn off the power once and then press it again to turn it back on.

To return to the previous step:

<9> To return to the previous step without fixing the setting, press the [▲1] input cancellation

key. Note that this is possible only before writing to the EEPROM.

To return to the normal operation mode:

<10>Simultaneously press and hold the [▲1] and [▼4] keys (shown in the figure in the “Assign-

ment of Keys for Calibration” section below) for about 2 seconds, or press the [POWER] key
to turn off the power once and then press it again to turn it back on.

10. How to Use the Carrying Case and Rubber Boot

■ The carrying case (B9108NK) may be used as follows:

(1) Undo the fasteners on the top

and sides of the case cover to
open it.

Note: The fastener on the logo-side cannot be undone.

■ Rubber Boot (93038) ■ Anti-skid pad

The optional rubber boot provides
shock protection and can be used
with a strap.

Note: When using the instrument with a rubber boot, the anti-skid pad at the bottom is not

needed. When used without a rubber boot in a leaning position, the supplied anti-skid
pad should be used.

(2) With the fastener on the logo-

side of the case centered, lift the
cover and pivot it to the side and
under the case itself.

Anti-skid pad

(supplied)

(3) Re-do the fasteners at the top

and sides of the cover.
