Range
CAUTION
When using the 10 mV range, do not apply external voltage or current. Doing so may damage
the voltage divider inside the 2553A.

ATTENTION
Avec une gamme de mesure de 10 mV, ne pas alimenter en tension externe, ni courant. Cela
pourrait endommager le diviseur de tension à l’intérieur du 2553A.
Procedure
Turn the
RANGE
dial to set the voltage, current, or resistance range.
• The indicator for the selected range illuminates.
• The unit corresponding to the selected range appears.

Example: 10 V
The 10 V indicator turns on.
Explanation
Source ranges are shown below. Set the value that you want to output (output setting) within the
selected range. For information on how to set the output setting, see section 5.2.
If you change the range when the output is on, the output turns off.
Voltage Ranges
Select from the following.
10 mV, 100 mV, 1 V, 10 V, 30 V
Current Ranges
Select from the following.
1 mA, 10 mA, 30 mA, 100 mA
Resistance Range
400 Ω.
Note
The 2553A does not have an auto range feature that automatically switches the range according to the
output setting.
