Model 187 & 189

Getting Started

Rotary Switch

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.

Each position is described in Table 1.

Pushbuttons

The buttons activate features that augment the function

selected with the rotary switch. The buttons are described

in Table 2.

Use the blue button ( %) to access functions labeled in

blue for some of the rotary switch positions. Table 1

defines all blue button functions.

Use the yellow button ( O) followed by other buttons

to access additional features. These features appear in

yellow above the appropriate keys. Table 2 defines yellow

button features. This manual identifies the yellow button

feature in parentheses following the button sequence .

For example, activating the FAST MN MX mode appears

as O M (FAST MN MX).

Model 187:
