Description of the working processes on the Dreiwag by a former naval assistant from the Kugelbake anti-aircraft battery. The WLV is not tied to any one location. It monitors the activities of the operating personnel and repeats all commands from the anti-aircraft commander that are relevant to the device. After the message "EM target detected", it orders the elevator and lateral rollers to "engage".

He summarizes the clear message from the three cylinders as "device is engaged". He immediately reports any malfunctions to the anti-aircraft commander, and immediately eliminates minor malfunctions during firing. When changing targets, he orders "disengage" and after acquiring "engage".

No. 1 is the E-meter. With No. 2 and No. 3 he picks up the target and reports "E.-M.. Target picked up". When the measuring mark is brought over the target, he reports "Set". He calls out all target movements: "Coming (walking, standing) target". He must turn the measuring wheel according to the trend.

No. 2 is the lateral alignment number. Before the device swings, he must ensure that the lateral roller is disengaged. He takes aim over the coarse sight until the E. meter has picked up the target. Then he looks through the eyepiece and keeps the target in the crosshairs by turning it evenly. When he hears "Stop, battery, stop!" he swings the device to zero degrees and ensures that the lateral roller is disengaged. He must pay attention to the blockage.

Nr.3 ist die Höhenrichtnummer. Sie fasst das Ziel der Höhe nach auf. Die Bedienung ähnelt der der von Nr. 2.

No. 4 operates the left TV side of the distance measurement. She sets the clockwork and adjusts it. On the target height setting she sets the target height that she receives from No. 10 and adjusts the corresponding curve bundle. During the run-up she sets the wind and ground TV, which are algebraically calculated, on the upper scale. On the lower scale she sets the improvements of the anti-aircraft conductor in "forward" and "backward", which are also calculated.

No.5 operates the Ewa. After the E-knife message "Set" it lifts the locking of the tangent handwheel, places the tangent on the last part of the curve and reports "Ewa set". When "Stop, battery, stop!" is heard, the tangent is placed vertically and the tangent handwheel is locked.

Nr.7 bedient die Seitenwalze. Sie stellt das Uhrwerk ein und reguliert es. Auf "Einkuppein" kuppelt sie die Seitenwalze ein und legt die Tangente an das letzte Stück der geschriebenen Kurve. Die linke Hand bleibt immer am Kuppelungshebel. Sie meldet vorher "Seitenwalze eingestellt". Kommt der Schlitten in die Endlage, kuppell sie aus und dreht ihn in eine günstigere Lage. Auf Halt,Batterie,Halt!” kuppelt sie aus. Sobald das Gerät in Nullstellung steht, stellt sie die Tangente senkrecht, Nr.8 bedient die Höhenwalze in der gleichen Weise wie Nr.7 die Seitenwalze. Sie muß auch die Verbesserungen des Flak-Leiters der Höhe nach einstellen, z.B. "10 höher!" oder "5 tiefer!”, "steht!".

No. 9 operates the TV drum. It keeps the measuring distance shown in the counter in line with the TV drum and the target elevation angle indicator. As soon as the E-meter has reported "set", it calls out the distance, later only from 5 to 5 km.

No. 10 operates the attachment drum. At the start of the run-up, it immediately determines the target height based on the announced measuring distance. In addition, it continuously adjusts the detonator setting time, which appears in the counter, to the point of impact at the relevant curve on the attachment drum.

No. 11 is the main BÜ and operates the triple improvement. She passes all the commands from the commander to the guns by telephone. As soon as she has received the spin and windage from No. 13, she sets these values. She must first convert the windage into the horizontal on the converter drum.

No. 12 is the salvo timer. It establishes the connection to the guns by ringing a bell following the commander's orders.

No. 13 operates the anti-aircraft windscreen. It determines the wind speed, the spin and the wind angle based on the distance announced. The wind speed calls out the wind angle and the spin of No. 11 to No. 4. Source: Harald Schönemann, Marinehelfer der Batterie Kugelbake 1943-1945
