Section IV – Operating Instructions
Front Panel Controls
Power -- Pushbutton
Push ON / Push OFF
RANGE/PUSH FOR MENU -- Rotary Control/Pushbutton
This is a multi-function button and should be thoroughly understood prior to operating any other controls
on the AVM-2000.
Range:
In the default position, meaning the rotary button was not pressed only rotated, the rotary control button
selects one of 21 full scale voltage ranges: 100 nV, 300 nV, 1 μ V, 3 μ V, 10 μ V, 30 μ V, 100 μ V, 300 μ V, 1
mV, 10 mV, 30 mV, 100 mV, 300 mV, 1 V, 3 V, 10 V, 30 V, 100 V, 300 V, 1 kV (1000 V). The selected
range full-scale value displays on the LCD.
Push For Menu:
This control performs secondary functions such as instrument setup routines. To access to these functions
depress the RANGE control for approximately 5 seconds, after which the set up menu appears in the LCD.
Rotating the RANGE control in this mode causes the LCD to display various setup options.
FILTER -- Pushbuttons
Two momentary action FILTER pushbuttons allow the user to increase (+) or decrease (-) the filter
setting. Filter integration time is shown on the LCD. The available filters: 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50,
and 100 seconds. An input signal is averaged (running average) before driving the meter movement or
isolated output over these times.
NOTE: Input ranges of 10
μ V and below have a restricted range of filter times (see Table 4-1).
