2.3.1.3
This setting is valid for Guardian 6100 Plus line leakage test only. Compensate is the LC
input voltage compensation in which a correction (% value) can be added to better
simulate what the true line leakage would be. The simulation correction value can be
programmed in whole number increments of ±(5-50%). Use the numerical keys then
[ENTER] to enter a compensate value in percent. The range is 5-50% and the default
setting is 20%.
2.3.1.4
The Automatic Gain Control (AGC) circuit is used to keep the output signal of a circuit
constant as the amplitude of the input signal varies. The Guardian 6000 Plus has two
Gain Control circuits: hardware and software. See Table 2-3 for gain control functions
based on output voltage.
50 – 5kV AC
50 – 499V DC
500 – 6kV DC
50 – 1000V DC (IR)
DC 50V AGC is the hardware gain control for DC voltages below 500V. To access DC
50V AGC, enter System Setup by pressing [MENU], [1] and the [↓] or [↑] arrow on the
keypad so the backlit box is to the right of DC 50V AGC. Use the function key [ON] or
[OFF] to turn the automatic gain control circuit ON or OFF. The default setting is OFF.
