signal will obscure the signal at the reference and make detection difficult if not impossible. See the SR850 Basics section for more information.

This key selects the Manual Reserve entry field for knob adjustment. Keypad entry is not allowed for this parameter. This menu box is availa- ble only if manual reserve is selected above. The reserve may be set between the minimum and maximum values in 10 dB increments. The min and max reserve limits change with sensitivity (see the table on the previous page). If the sensitivity is changed, the manual reserve may also be changed as described above.

Auto Reserve

Time Constant

Pressing [AUTO RESERVE] will change the reserve to manual and adjust the dynamic reserve to the minimum reserve required. Auto Reserve will not work if there are low frequency noise sources which overload infrequently.

This key selects the Time Constant as the active field. Use the knob to adjust the time constant. Keypad entry is not allowed for this parameter. The time constant may be set from 10 µs to 30 s (det. freq.>200 Hz) or 30 ks (det. freq. <200 Hz).

The maximum time constant is 30 s if the detection frequency is above 200 Hz and 30 ks if the frequency is below 200 Hz. The actual range switches at 203.12 Hz when the frequency is increasing and at

199.21Hz when the frequency is decreasing. The time constant may not be adjusted beyond the maximum for the present detection frequency. If the frequency is below 200 Hz and 100 s is the time constant and the fre- quency increases above 200 Hz, the time constant WILL change to 30 s. Decreasing the frequency back below 200 Hz will NOT change the time constant back to 100 s.

The absolute minimum time constant is 10 µs. The actual minimum time constant depends upon the filter slope and the DC gain in the low pass filter (dynamic reserve plus expand). The minimum time constant is only restricted if the dynamic reserve plus expand is high and the filter slope is low - not a normal operating situation. The tables below list the mini- mum time constants for the different filter slopes and gains.
