Rel Function; Max/Min Function; Auto Power Off Function - VOLTCRAFT R-200 Bedienungsanleitung

REL Function

The REL function is only active in the 4-lead resistance measurement ranges
(400 mΩ, 4Ω or 40Ω).
The REL function allows a fast relative measurement, e.g. to display component tolerances. The refer-
ence component is measured and saved in the internal memory and then automatically deducted from
subsequent measurements. This allows the easy display of the deviation from the reference compo-
nent.
- Attach the object to be measured as per "Resistance measurement with 4-lead measurement proce-
dure" to the Kelvin measuring leads. Select the fitting measurement range and wait until the dis-
played value has stabilised.
- Press the "REL" button (4) in operating mode. "REL" appears in the display and the display is reset to
zero. The reference value is saved.
- Continue to carry out the difference measurement on the other measurement objects.
- Pressing the "REL" button again allows the control display of the saved value. The display will flash
"REL". Pressing this button again switches back to the REL measurement mode.
- To exit the function, hold down the "REL" button for approx. 1s until "REL" disappears and the meter
beeps.
If the measurement range is changed or the measurement function is altered the REL memory
is deleted.

MAX/MIN Function

This function shows the minimum and maximum measured values in the display. The automatic range
selection (display shows "MANU") is deactivated.
- Press the "MAX/MIN" button (2) in operating mode. "MAX" appears in the display and the highest val-
ue is displayed.
- Press the "MAX/MIN" button again to switch to "MIN". The lowest value is shown
- Pressing the "MAX/MIN" button again cause the display to flash "MAX MIN" and the current mea-
sured value is displayed. The MIN/MAX memory continues to operate in the background.
- Every time you press the button you switch the display.
- To exit the function, hold down the "MAX/MIN" button for approx. 1s until "MAX", "MIN" or "MAX MIN"
disappears and the meter beeps.

Auto Power OFF Function

The DMM turns off automatically after 30 minutes if no button or switch is operated. This function pro-
tects the battery, saves battery power and extends the service life.
To reactivate the DMM after automatic shutdown, use the dial switch or press any function button (apart
from the light button (6)).
