c) RANGE function
The RANGE button allows you to switch from automatic range selection (AUTO) to manual range selection. This is
necessary if the wrong range is selected or the multimeter keeps switching between two ranges.
Press the “RANGE” button to select the next measuring range (if the highest measuring range is selected, the multi-
meter will go back to the lowest range).
To disable manual range selection, hold down the “RANGE” button for approximately one second. This will re-enable
automatic range selection. Manual range selection is enabled when “AUTO” is not displayed.
d) REL function
The REL function allows you to take a reference measurement to avoid possible line losses (e.g. during resistance
measurements). This function resets the current measurement to zero.
Press the “REL” button to enable this mode and save the reference value. “REL” will appear on the display. The
display will be reset to zero and automatic range selection will be disabled.
To disable this mode, press the “REL” button again or change the measuring mode using the rotary dial.
The REL function is not available in the following modes: Continuity test, diode test, frequency and
pulse ratio.
e) LED light
When the DMM is switched on, the side-mounted light button (L) can be used to switch the LED light on and off.
Hold down the button for approximately 2 seconds to switch the light on/off. The light will stay switched on until it is
switched off using the light button (L), or until the multimeter is switched off with the rotary dial (“OFF” position) or the
automatic power-off feature.
