If the measuring object is connected, the exact measured value is displayed. Fluctuations in the displayed value by some digits are systemic and within the tolerance.
If you have selected the resistance measuring range, the continuity testing range or the diode test and the measuring input is open, the overflow indication will be displayed.

IMPORTANT INFORMATION ON THE MEASURING PROCESS!
Warning of electrical voltage
Improper handling of the measuring device entails a risk of electric shock!

Before carrying out voltage measurements, observe the following:

• Never apply a voltage exceeding the rated nominal voltage of the measuring device between the connections or between the connections and earth (see imprint on the housing).
• Check the measuring tips for damaged insulation and for continuity. Replace damaged measuring tips.
• Check the insulation of the measuring device sockets.
• Before commissioning, check the function of the device at a known voltage source, e.g. on a known and safe 230 V voltage source or on a known and safe 9 V battery.
• First connect the measuring tip connected to earth and afterwards the live measuring tip. When disconnecting the measuring tips, proceed in reverse order, i.e. disconnect the live measuring tip first.
• Prior to every voltage measurement make sure that the measuring device is not set to the current measuring range.
• If the device indicates an exceedance of the measuring range (OL) immediately after being connected to the measuring object, first switch off the circuit at the measuring object, then immediately remove the measuring tips from the measuring object.
• Do not switch any motors in the measuring circuit on or off during a measurement. Voltage peaks caused by a switch- on or switch-off can damage the measuring device.
