Fluke 87 IV Multimeter
The Fluke Model 87 and Model 89 Series IV True RMS Multimeters (hereafter referred to as the “meter”) comply with:

EN61010.1:1993
ANSI/ISA S82.01-1994
CAN/CSA C22.2 No. 1010.1-92
1000V Overvoltage Category III, Pollution Degree 2
UL 3111-1

Turning the Meter On
To turn the meter on, turn the rotary switch from OFF to any switch setting.

The ac volts function is assumed in the following discussion. You do not need connections to the input terminals at this time.

If you want a view of the full display (all segments illuminated), press and hold Q while turning the meter on. Release the button when you are done viewing the full display.

Battery Considerations
The meter uses four AA alkaline batteries. The following paragraphs describe several techniques used to conserve battery power.

Automatic Power Off
The display blanks and the meter goes into a “sleep” mode if you have not changed the rotary switch position or pressed a button for a set period. While in Sleep mode, pressing any button turns the meter on. The meter then returns to the display for the function selected with the rotary switch; all previously activated button features (HOLD, Hz, etc.) are discarded.

The automatic power off is preset to 15 minutes. From the setupmenu, you can specify a maximum period of 23 hours, 59 minutes. If you set the period to 0, the meter remains on until you turn the rotary switch to OFF or the batteries become too weak.

Automatic Backlight Off
select A backlight level (low, high, or off.) In low or high, the backlight turns off automatically after a given period. This period is also preset to 15 minutes and can be set to a maximum of 99 minutes from the setup menu. If the period is set to 0, the backlight is on indefinitely and can only be turned off by pressing T or turning the meter off.

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.
