2. Connect the voltage output of the AC voltage/current standard to the voltage
input terminal of this instrument. Connect the H terminal of the standard to the V
terminal of this instrument, and connect the L terminal of the standard to the ±
terminal of this instrument.
3. Set the output voltage of the standard to 30.00 V and output this voltage.
4. Press the ENTER key after the value on display C stabilizes.
5. Display B will change to "300.0" V.
6. Set the output voltage of the standard to 300.0 V.
7. Press the ENTER key after the value on display C stabilizes.
8. Turn the output of the standard OFF.
This completes the adjustment of the voltage range. The current range will be
adjusted next. If the current range is not to be adjusted, press the SHIFT key
here.
Adjusting the Current Range
1. After having completed adjusting the 300 V voltage range, display B will show
"100.0" A.
2. Connect the current output of the AC voltage/current standard to the current
input terminal of this instrument. Connect the H terminal of the standard to the A
terminal of this instrument, and connect the L terminal of the standard to the ±
terminal of this instrument.
3. Set the output of the standard to 100 mA and output this current.
4. Press the ENTER key after the value on display C stabilizes.
5. Display B will change to "1.000" A.
6. Set the output of the standard to 1.000 A.
7. Press the ENTER key after the value on Display C stabilizes.
8. Display B will change to "10.00" A.
9. Set the output of the standard to 10.000 A.
10. Press the ENTER key after the value on display C stabilizes.
11. Turn the output of the standard OFF.
12. Press the SHIFT key and display C will change to "rAnGE". This completes the
range adjustments. When you press the RESET key instead of the SHIFT key,
the carried out adjustments will become invalid.
• In case the External Input Option is installed (/EX1 or /EX2)
1. Select "Ein" in step 2 of Preparing this instrument (see previous page) and press
the ENTER key.
2. Display B will change to "10.00" V (or "200.0" mV).
3. Connect the voltage output of the AC voltage/current standard to the voltage
input terminal of this instrument. Connect the H terminal of the standard to the
EXT terminal of this instrument, and connect the L terminal of the standard to
the ± terminal of this instrument.
4. Set the output voltage of the standard to 10.000 V (or 200.00 mV) and output
this voltage.
5. Press the ENTER key after the value on display C stabilizes.
6. Press the SHIFT key and display C will change to "Ein". This completes the
external input adjustments. When you press the RESET key instead of the
SHIFT key, the carried out adjustments will become invalid.
Note
The displayed value of the external input will become 50.000 A by the rated range.
