| * a. The digital display reads out the total integrated charge in Coulombs * Multiplier (including the decimal point). The pre-scaler value (h) is automatically included in the display by moving the decimal point in the display readout. For example, if the digital display reads 1234.56 and the range is 10**-6 the charge is 1234.56 uC. | * a.

| * p. This switch when up will reset the Beam Current Integrator to 0 if the Reset Enable switch (o.) is up. No integration will take place until this switch is down. The external reset BNC will reset the Beam Current Integrator when a +5 volt level is applied to the external reset input AND the Reset Enable (o.) switch is up. | * p.

| + | * s. This is a SPARE (unused) switch. | ||
| + | * t. Fast (F) / Slow (S) meter response. This switch will allow averaging the indicated beam current for unsteady beams. | ||
| + | * u. This is a SPARE (unused) switch. | ||
| + | * w. Preset Charge (Enable Disable). This switch will allow stopping the integration and providing a control output level (Integrate Control Output) when the integrated charge display matches the digits in the 6 thumbwheel Preset (i.) switches when in the Enable position. When in the Disable position, integration will not stop if the switches match and the digital diaplay will wrap around from 999999 to 000000. | ||
