5. Operation Note: Before operating the device, you must read, understand, and follow all instructions, dangers, warnings, cautions, and notes. Note: When the meter is not in use, the function switch should be set to the OFF position. Note: When connecting the probe leads to the device under test, connect the COM (negative) lead before connecting the positive lead. When removing the probe leads, remove the positive lead before removing the COM (negative) lead. 5.1 Powering the Meter 1.
5.3 Auto/Manual Range Mode In Auto range mode, the meter automatically selects the most appropriate measurement scale. In Manual range mode, the desired range (scale) is set manually. Auto range mode is the default mode of operation. When a new function is selected with the function switch, the starting mode is Auto range and the indicator is displayed. To enter Manual range mode, press the button. To change the range, press the repeatedly until the desired range is displayed.
5.6 Continuity Test Warning: Do not do diode, resistance or continuity tests before removing the power from capacitors and other devices under test during a measurement. Injury to persons can occur. 1. Set the function switch to the position. button to select continuity measurement. The indicator will be displayed. 2. Use the 3.

5.11 Extended Functionality In addition to the basic measurements, the meter can be set to different modes for extended functionality. 5.11.1 Selecting the Mode The mode icons applicable for the selected measurement type are displayed in the lower part of the display. When a mode is enabled, the icon is framed. Figure 5.2 Mode icons (AC voltage measurements): Peak mode and Silent mode are enabled. 1. Press the or button to navigate to the desired mode icon. The currently selected icon will flash. 2. 3.
5.11.5 Frequency mode (ACV and ACA only) In Frequency mode, the frequency is displayed in the main display and the period is displayed in the secondary display. Frequency mode is available when measuring AC voltage or current. 1. Select and enable Frequency mode as described in section 5.11.1 Selecting the mode. 5.11.6 Relative mode In Relative mode, the difference between the current reading and a stored reference value is displayed in the main display.
5.11.9 Setup Mode In Setup mode, you can define the settings for various meter options: Auto power off (indicated by the text APO): A mode where the time period after which the meter enters sleep mode can be set. The range is 1 to 30 minutes, or OFF. The factory default is 10 minutes. Auto backlight off (indicated by the text b.Lit): A mode where the time period after which the backlight turns off can be set. The range is 1 to 30 minutes, or OFF. The factory default is 5 minutes.
5.12 Normal Hold Mode and Auto Hold Mode The meter has two types of hold modes: normal hold mode and auto hold mode. 5.12.1 Normal Hold Mode In Normal hold mode, the meter freezes and displays the last reading from the main display and continues to display this value. button. In Hold mode, the To enter/exit Normal hold mode, press the displayed. indicator is 5.12.2 Auto Hold Mode In Auto hold mode, the secondary display freezes the last reading from the main display and continues to display this value.
6. Maintenance 6.1 Cleaning and Storage Clean the meter with a damp cloth and mild detergent; do not use abrasives or solvents. If the meter is not to be used for an extended period, remove the batteries and store them separately. 6.2 Battery Replacement The Battery symbol flashes with no ‘bars’ when the batteries have reached a critical level of 7.0V. The symbol stays active and visible while the LCD is powered. The meter displays readings within specifications while the low battery indicator is on.
