tions”).
To access the ohms configuration menu, press CONFIG then OHMS. Use

which is shown in Figure 4-1. Menu items include:
• SOURCE — Select AUTO or MANUAL source mode.

• GUARD — Choose OHMS or CABLE guard.
• OFFSET COMPENSATION — Enable or disable offset-compensated
ohms (not valid for Model 2430 Pulse Mode).

The following paragraphs discuss each of these aspects in detail.
