The "AGMS Pre-Pulse Mode" algorithm is designed to accommodate the initial pre-heat kV pulses

commonly found with some dental generators such as the Gendex 770. Pre-Pulse ON should not be

selected for other pulsed waveforms such as pulsed fluoroscopy or tomography.

Note: The dose remains integrated over the entire exposure regardless of the setting (On or Off), only the

kV and time calculations are affected. Advice: The Accu-Gold default setting is AGMS Pre-Pulse Mode

"Off". If the correct number of pulses is not being reported, select "Settings" and then turn On "AGMS Pre

Pulse Mode" and repeat the exposure.

The Accu-Gold Pre-Pulse algorithm automatically detects the correct trigger threshold and eliminates pre-

heat pulse counting. The duration and pulse count are reported excluding the pre-pulse region. KVp is

calculated over the last 60% of main exposure. Dose is calculated for the entire exposure, including the

pre-pulse region.

Many modern x-ray generators now feature scout exposures which may introduce gaps of several seconds

or more in the radiation output. The default end of exposure timing for Accu-Gold is 3 second for Diagnostic

and Mammographic sensors. In some instances, this is not long enough and Accu-Gold may attempt to

display the exposure results while the generator is finishing the exposure. If this situation is encountered,

you may select an end of exposure delay of up to 8 seconds. 'Min' allows one to make successive

measurements quickly. In between measurements, zeroing is skipped therefore use 'Min' with large

signals only where zeroing in between measurements is not important – use with "High Threshold".
