To Copy a Channel Configuration

After configuring a channel to be included in the scan list, you can copy that same configuration to other channels in the instrument (including digital channels on the multifunction module). This feature makes it easy to configure several channels for the same measurement. When you copy the configuration from one channel to another, the following parameters are automatically copied to the new channel:

•Measurement configuration

•Mx+B scaling configuration

•Alarm configuration

•Advanced measurement configuration

1Select the channel to copy the configuration from.

Turn the knob until the desired channel is shown on the right side of front-panel display. For this example, let’s copy the configuration from channel 103.

2Select the copy function.

Use the knob to scroll through the measurement choices until you see

COPY CONFIG. When you press to make your selection, the menu automatically guides you to the next step.

3Select the channel to copy the configuration to.

Turn the knob until the desired channel is shown on the right side of front-panel display. For this example, let’s copy the configuration to channel 105.

4Copy the channel configuration to the selected channel.

Note: To copy the same configuration to other channels, repeat this procedure.
