| PIN | SIGNAL |
| 1 | GND |
| 2 | COS |
| 3 | SIN |
| 4 | Zero pulse |
| 5 | Trig. Zp. |
| 6 | GND |
The Sin-Cos signal amplitudes at the pin's 2 and 3 are dependent of the detectors-current. The conversion ratio is 301mV/uA., this signal is specified in uA because of the voltage drop in the supply cables. According to the manufacturer this signals should be 22 +/- 8 uApp.
Example: If the COS Signal amplitude = 7.5 Vpp., measured at the test point P2 pin 2, the detector current will be:
The admitted voltage measured on the IK 320.1 board would be:
| RANGE | Vpp | Volt | uA |
| Min. | 4.22Vpp. | 1.5 V. | 14 |
| Average value | 6.61Vpp. | 2.344 V. | 22 |
| Max. | 9Vpp. | 3.19 V. | 30 |
The lamp lifetime is some how inverse-proportional to the voltage supply, the lower voltage the longer lamp-lifetime.
