„MIN/MAX“ detection of the highest and lowest measured values
„TIME“ internal clock; the indication is in minutes and seconds up
to one hour and beyond this in hours and minutes. Maxi-
mum indication 23:59 (23 hours, 59 minutes)
„LMT“ "LIMIT" = comparative measurement with selectable upper
and lower limits (VC 670 only)
„PH“ "Peak Hold" = peak value measurement indication (VC 650
and VC 670 only)
„REC“ "Record" = record/store a measured value; there are 10
memory locations available. The number of the current
memory location is shown on the extreme left of the dis-
play.
„RCLL“ "Recall" of a stored measured value. For memory location
details see "REC" above
remaining positions
„HOLD“ "Data Hold" = the measured value is held (e.g. pending
transcription) until the "HOLD" button is pressed again or
the DMM switched off..
„AUTO“ is displayed when automatic range control is active.
„TONE“ tone signal for measured value recognition (VC 670 only)
„TRIG±“ trigger button for frequency measurement. Triggering on
the positive "+" or negative "-" edge of the signal to be
measured.
„Logic“ logic function display (VC 650 and VC 670 only).
„HI“ high logic level measurement
„LO“ low logic level measurement

„
Æ
%“ stands for "REL" = relative value measurement; possible
with ACV, DCV, Ohm, continuity, diode test, capacity, mA,
uA and A. The difference relative to a certain measured
value is displayed. The function is switched off by pressing
the "ENTER" button.
