Fluke 189 user manual Rotary Switch

Model 187 & 189

Users Manual

Rotary Switch

The rotary switch is shown in Figure 2-2. Each position is described in Table 2-1.

Turn the meter on by selecting any measurement function (identified with white letters around the rotary switch). The meter presents a standard display for that function (range, measurement units, modifiers, etc.) The display may also be influenced by some of the choices made in Setup.

Use the blue button to select any rotary switch alternate function (labeled in blue letters). You can also use other buttons to choose modifiers for the selected function.

When you turn the rotary switch from one function to another, a display for the new function appears. Button choices made in one function do not carry over into another function.

With Model 189, a VIEW MEM switch position is available; refer to Chapter 4 for more information.
