Configuring a Measurement Channel

Configuring a Channel to Measure Resistance

Perform the procedure in Figure 2-6 to configure a channel for measuring resistance. In preparation, the instrument must be in the inactive mode (not scanning or monitoring) and the desired channel must be selected (see Figure 2-3). To exit at any time (changes not saved), press the Ckey.

The resistance to be measured can be connected using one channel (two-terminal connection) or two channels (four-terminal connection). The four-terminal connection provides increased measurement precision. The two channels used in a four-terminal connection are a decade apart (n and n+10), for example, channel 3 (n) and 13 (n+10). Only the lower channel is configured.

Restrictions

Four-Terminal Channels. Four-Terminal configurations are limited to channels 1 to 10

(n). The channel a decade higher (n + 10) is automatically reserved for use.

Selecting the Resistance Mode. Press the FUNC key to access the SET FUNC (Set Function) menu. Press the up/down arrow keys until Ω (ohms) is displayed, then press the ENTER key.

Selecting the Measurement Scale. Select a fixed scale or Auto (autoranging). A fixed scale indicates an upper measurement limit. For example, the 30.000 kΩ scale measures 30 kΩ ohms or less. Measurements beyond the scale limit will cause an OL (overload) display. The x1 (unity or x 1) multiplier indicates a reading in ohms; the k (kilo or x 1,000) multiplier indicates a reading in kilohms; the M (mega or x 1,000,000) multiplier indicates a reading in megohms.

In Auto (autoranging), the instrument chooses the scale for the best measurement resolution. When scales are changed, the scan is momentarily slowed.

Selecting the Terminal Mode. Select the two- terminal (2T) or four-terminal (4T) mode. 4T automatically clears configuration data from the channel a decade higher (n+10). For example, selecting channel 3 for 4T operation will automatically clear channel 13 of all configuration data and lock it out from further use.
