General data

5.1 General data on multimeter
5.1.1 The digital display is designed as a 4 digit liquid-crystal indicator with 14 mm
digit height and decimal point. The highest value displayed is 6000.
5.1.2 The bar graph display consists of 62 segments.
5.1.3 The polarity indication  functions automatically. Only a polarity con-
trary to the socket definition is indicated, as "-".
5.1.4 The range overload will be displayed with "OL" or "-OL" and sometimes
with an acoustic signal.
Attention: no display or warning by complete overload.
5.1.5 The "RANGE" key  can be used to change over to the manual meas-
uring ranges and to hide "AUTO" on the display at the same time. By
pressing the key for approx. 2 seconds, the automatic range selection is
activated ("AUTO" on the display).
5.1.6 Volt sensor key  : The voltage indicator function is intended for local-
izing AC voltages to earth (see 8.9).
5.1.7 The "MIN/MAX" key  function records and stores the highest and low-
est measurements automatically. By pressing the button several times,
the following values are shown: Display "MAX/MIN" shows the current
measurement value, "MAX" shows the highest value stored and "MIN"
the lowest value stored. The "HOLD" key serves to interrupt the "MIN/
MAX" function. When the key is pressed for 2 sec. the unit switches
back to normal mode. Press the "MIN/MAX" key  for 2 seconds to
switch over to the "PEAK" function (peak value storage). The "PEAK"
function detects and stores the positive and negative peak/ crest
value (> 1 ms) in the mV, V AC/ DC and mA, A AC/ DC function. The
automatic range selection is deactivated in the MIN/ MAX and PEAK
function.
5.1.8 "Smart HOLD" - storage of measurement reading: When the "Smart
HOLD" key  is pressed, the measurement reading is stored in the
memory. The symbol "HOLD" appears in the display at the same time.
If the measured value increases by 50 digit above the saved value the
change in measured value is shown by a blinking display and by a
signal tone. (changes of measured values between AC and DC voltage/
