6.12 Applying a Bias on the Measuring Input Signal
This section explains the details of setting a bias on the measuring input signal.
If you change the input range, set the bias again.
Procedure
1. Hold down the MENU key for 3 seconds to enter Setting mode.
2. Press the key or SHIFT + key to select Bias and then press the key.
3. Set each item and press the key.
Use the key or SHIFT + key to select values.
For the procedure on how to enter values or characters, see section 4.2.
If you press the ESC key in the middle of the operation, the settings entered up
to then are cancelled, and the display returns to a higher level menu.
4. When the Setting complete screen appears, do either of the following:
Press the key to set other channels.
If you are done, press the ESC key.
5. Hold down the MENU key for 3 seconds to return to Operation mode.
Select whether to use the bias.
Set the bias value.
Set the channel range.
The new setting takes effect.

Explanation
Channel Range
The only case when a bias can be set on multiple channels simultaneously is when the
channels are set to the same range type (for example channel 01 and 02 are set to 2 V
range). For channels on which scaling is set, the channels must be set to the same
range type, same span values, and same scaling values.
Bias
The range of bias that can be specified is ±10% of the span of the measurable range at the
specified range type. For example, the range is –0.4 V to 0.4 V for the range type 2 V.
For channels on which scaling is set, the range is ±10% of the scaling span.
Note
A bias cannot be set on channels set to ON/OFF input (DI).
