From the Setup menu see Chapter 5 , 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. Press T to select the 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.

A constant battery icon B in the upper left corner of the display notifies you that the batteries are low and should be replaced. To avoid false readings, which could lead to possible electric shock or personal injury, replace the batteries as soon as the battery icon B appears. A flashing battery icon means that battery failure is imminent. The backlight cannot be used in this condition.

For Model , logging and communications also cease. 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. The rotary switch is shown in Figure Each position is described in Table The buttons activate features that augment the function selected with the rotary switch.

The buttons are shown in Figure and described in Table Table 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 defines yellow button features.

This manual identifies the yellow button feature in parentheses following the button sequence. Model only. See Chapter 4 for more information. Press to turn backlight on or off. Also, in Setup, use the arrow function l to select the previous digit or item in a list. Press to start retaining min, max, and average values. Press successively to display max, min, and average values. Press to store the present reading as an offset reference; subsequent readings show only the relative difference from this value.

Press again to show the difference as a percentage of the reference. Press to access Setup selections. Press to store a Setup selection and proceed to the next selection. These selections all use a specific fixed range. Autoranging AUTO lighted in the display always comes on initially when you select a new function.

The bar graph provides an analog indication of the measured input. For most measurement functions, the bar graph updates 40 times per second. Since this response is much faster than the digital display, the bar graph is useful for making peak and null adjustments and for observing rapidly changing inputs. When multiple features are active, the secondary display shows one of the values. For example, Hz could appear in the secondary display while dB appears in the primary display.

In normal operation 0 zero is on the left. The polarity indicator left of the bar graph shows the polarity of the input. Both polarity. Percent difference in Relative mode is being displayed in the primary display. The primary display has been modified by the reference value shown in the secondary display. Indicates negative readings. In Relative mode, this sign indicates that the present input is less than the stored reference.
