PDF Contains
Technical Data, Mechanical data, Detailed Circuit diagram with components value, PCB layout. Actual PCBs Print. Component List, Spare parts code list and Input output detail. It cover LBB1211, LBB1212, LBB1213, LBB1216, LBB1217.
It is the actual Service Manual for SQ10
;
very good manual with clear electrical schemes. Very helpful to find wat was wrong inside my microwave.

Hi, thankyou for providing the Nordmende Globetrotter original manufacturer's repair manual. Quality is very good and sharp - the PDF file was comfortably small to download. The only question is: why did it take so long to become ready for download?? Many thanks anyway, I fixed the fault in the radio thanks to the circuit.
regards: Nick

This was super service.Ordered this manual and was reading the download an hour later
;
as always, rapid and efficient, very good and clear prints
details clearly visible keep going this way!!!!!!
MEASUREMENT AND TEST
1. MEASUREMENT OF THE MICROWAVE POWER OUTPUT
M icrowave output power can be checked by indirectly m easuring the tem perature rise of a certain am ount of water exposed to the m icrowave as directed below. PROCEDURE 1. M icrowave power output m easurem ent is m ade with the m icrowave oven supplied at rated voltage and operated at its m axim um m icrowave power setting with a load of 1000 ± 5cc of potable water. 2. The water is contained in a cylindrical borosilicate glass vessel having a m axim um m aterial thickness of 3 m m and an outside diam eter of approxim ately 190 m m . 3. The oven and the em pty vessel are at am bient tem perature prior to the start of the test. The initial tem perature of the water is 10 ± 2 ° C (50 ± 3.6 ° F). It is m easured im m ediately before the water is added to the vessel. After addition of the water to the vessel, the load is im m ediately placed on the center of the shelf, which is in the lowest norm al position. 4. M icrowave power is switched on. 5. Heating tim e should be exactly A seconds. (Refer to table as following) Heating tim e is m easured while the m icrowave generator is operating at full power. The filam ent heat-up tim e for m agnetron is not included. 6. The initial and final tem perature of water is selected so that the m axim um difference between the am bient and final water tem perature is 5K. 7. The m icrowave power output P in watts is calculated from the following form ula: P = 4187 X
T
T is difference between initial and ending tem perature. t is the heating tim e.
The power m easured should be B (Refer to SPECIFICATIONS) W ± 10.0 % .
CAUTION
1. W ater load should be m easured exactly to 1 liter. 2. Input pow er voltage should be exactly specified voltage (R efer to S PE C IFIC ATIO N S ). 3. A m bient tem perature should be 20 ± 2° C (68 ± 3.6 ° F)
Heating time for power output:
A (second) B (W ) 70 600 64 650 60 700 56 750 52 800 49 850 47 900 44 950 42 1000 40 1050 38 1100
