Entering Values with Prefix Units
If a prefix unit is shown as in “Offset” in the above example (“k” of “kV”), you can enter
not only the value but also the prefix unit from the USB keyboard.
The items for which you can enter prefix units are voltage (V), time (seconds: s), and
current (A).
• Entry Example
• Entering 1 for the Offset in the example above is equivalent to entering 1 V, and
the screen displays 1000 mV or 1.0 V.
• Entering 1, 0, m for the Offset is equivalent to entering 10 mV. The screen displays
10 mV, 0.01 V, and so on. In this case, the setting takes effect from the point at
which the prefix units are entered, so you do not have to press the Enter key.
