Range Function, Manual Measurement Range Selection; Rel Function; Hold Function - VOLTCRAFT VC880 Bedienungsanleitung

9. RANGE FUNCTION,
MANUAL MEASUREMENT RANGE SELECTION
The RANGE function enables manual measuring range selection in some measuring voltages with an automatic mea-
suring range selection (AUTO). In threshold areas, the measuring range should be set firmly to prevent undesired
switching.
Press the "RANGE" button to activate this function. "AUTO" goes out in the display, and "MANUAL" appears.
Press the "RANGE" button for 2 seconds to switch off this function. "AUTO" appears again in the display (if the autor-
ange function is available for his measuring range).

10. REL FUNCTION

The REL function allows a reference value measurement to avoid possible line loss as it occurs, e.g., during resis-
tance measurements. For this purpose, the current indicated value is set to zero. A new reference value is set. The
basic value (rel difference) is displayed in the upper, small display.
Press the "REL/PC" button to activate this measuring function. The display indicates " ". The automatic measuring
range selection is deactivated now.
In order to switch off this function, press the "REL/PC" button again or change the measurement function.
The REL function is not active in the measuring ranges for temperature, continuity tests, diode
tests, frequency and low-pass filter voltage measurement.

11. HOLD FUNCTION

The HOLD function freezes the currently indicated measured value to allow you to read or
record it easily.
If you test live wires make sure that this function is deactivated before the measurement starts.
Otherwise, the measurement will be incorrect!
To switch on the Hold function, press the "H" button (10); a signal sound confirms this command and "H" appears on
the display.
In order to switch off the HOLD function, press the "H" button again or change the measurement function.
