ADAPT range (ADP)
Indication : 10 units of the lowest digit per mV.
Accuracy : ±(0.3% + 2D)
Input protection : 600Vd.c. or 600Vrms
4. Display and connections
The display, controls and test jacks are shown in Fig.1.
1. Digital display — The 33⁄4 digit 3999 count digital LCD display includes a 42-element analog bargraph display and has
automatic annunciators for polarity, decimal point, range overrun, store data, AC/DC, Ω/ "<", " Auto",
"
>", , REL. MAX. MIN. and unit symbols.
2. Rotary function and range switch — This switch is used to select functions and measuring ranges.
3. COM input terminal — Input for the common potential.
4. V-Ω input terminal — Input for voltage and resistance measurement, diode testing, and capacitance, frequency and
ADP measurement.
5. mA input terminal — Input for milliampere current measurement.
6. A input terminal — Input for current measurement. The meter can measure currents of up to 20A but the time is then limited
to a maximum of 30 seconds.
7. Function button (blue) — This button is used to switch between a.c. and d.c. voltage and a.c. and d.c. current, between
resistance measurement and continuity testing, between diode testing and capacitance
measurement, and between frequency and ADP measurement.
8. MIN.MAX button — Pressing the MIN/MAX button selects the MIN/MAX store mode. The minimum and maximum values are
then reset to the level currently measured. The display annunciators "
>" and "MAX" or "MIN" are
activated. In the MIN.MAX mode the minimum or maximum values are stored. The internal sounder will
operate if a new minimum or maximum value overruns the display capacity of 4000 units.
