^^^^^ only if the eyes are off.
With them on the CON is overridden, so the C DEL + CON + COFF = Cycle time won't apply if you turn on the eye. The only way is to put fresh batteries in everything, then go shoot it as fast as you can. I would use PSP mode to make it easier.
The display will tell you the ROF. Then as GeeTee suggests, increase the COFF until you get the required ROF. Confirm the ROF with a Chrono.
Edit: Just found this originally from Nicky T:
E2 / Zero B
1. Fit fresh batteries to the loader that will be used and set the loader speed as required;
2. Enter the Setup menu;
3. Select [MODE] and choose the RAMP 3** option;
4. Set the COFF parameter to 40ms;
5. Enable the breech sensor;
6. Shoot the gun so that it ramps and measure the ROF on a rate of fire meter;
7. Adjust the COFF parameter and repeat 6 until the ROF is 11.8bps* (increasing COFF reduces ROF);
8. Check that CDELAY + CON + COFF is greater than 84ms and if not then increase CON;
9. Exit the Setup menu;
10. Check the rate of fire on a league approved ROF meter.
