2.3.1
O I
, Power
The
O I
key toggles the Model 2835-C on and off. To turn the meter on, depress
the
O I
key in until it clicks and stays in its depressed position. To turn the
meter off, press the key again until it clicks and rebounds to its original length.
2.3.2
SHIFT
When SHIFT is pressed, the SHIFT display annunciator lights and the blue key
functions (such as STOREF) are enabled. The next key press will cause that
blue function to be executed and the “shift status” to disable.
2.3.3
DISP , Display Brightness
This key cycles the display and the backlit key pad through: OFF, LOW, NORM
and HIGH brightness levels. This allows a user to operate in a dark environ-
ment without light pollution from the display, (except for one dim scanning
decimal point and the measurement activity annunciator).When the display is
OFF, the R/S, R/S A, or R/S B keys may be used to manually trigger measure-
ments. Any other key press returns the display to the LOW brightness state
while ignoring the key function.
2.3.4
FILTER, Signal Filtering
Press this key to cycle input signal filtering between: OFF, ANLG, DIG,
ANLG+DIG. This function provides methods of lowering the noise observed in
the measurement data and the analog output. When the ANLG annunciator is
lit, a 5Hz low pass filter lowers the noise floor by attenuating high frequency
signal components. ANLG filtering is not available to High Power detectors,
Energy detectors or any P-P modes.
When the DIG display annunciator is lit, measurements pass through a moving
10-sample averaging buffer before being further processed, stored or communi-
cated to the display or computer interfaces. With DIG on, all observable values
represent digitally averaged results relative to the original A/D conversions.
This averaging is independent of the subsequent processing available through
the STATS buffer, Section 2.3.15.
