- Page 5 Calibration Zero adjust First put on the red cap onto the modulator system. Then press in the EFM115_ReadOut Software the “Zero Adjust” button. If an error message appears, you should make a Zero adjust by the potentiometer (4) on back of the unit. Adjust the measure value < 50mV and press the “ok” button at the software.
- Page 6 By high voltage measurements the directives of the standard EN 10100 are be followed. For using the MK1 mount it on the modulator system of the EFM 115. At the voltage head MK11 there is a PTFE isolate field plate in 1cm arranged.
- Page 7 Grounding Grounding The appliance must be grounded to get real measuring results. You can connect ground by the 4mm socket on the back. Maintenance Don´t touch the modulator system! Time by time the modulator-system needs to be cleaned and a new offset – adjustment with shielded field-plate is necessary.
