Yesterday have I the last Platinen drawings after which RH1 is built got.

Here now the setupinstruction for my E meter, called RH1.
- All Potis shall take to middle position first.
- The 5 volts are adjust with R50.
- The 7,65 volts, this should be adjusted as exactly as possible with R55.
- Adjust the 6 volts of tension with R2, measured over R2.
All tensions are right now.

- R10 is now as long as altered till to measure a tension of 0.500 volts on R15 is.
On the PC Terminal attach 5000 ohms.
- TA must be moved, so that the needle points to set.
- TA Button  is screwed in tight now at 2 pointing.
-  A:  Turn the TA Button on 3 keily and attach a 12500 ohms resistance to the PC
   terminal. Taking the needle to set with R7.
- B: Turn the TA Button on 2 keily and attach a 5000 ohms resistance to the PC
   terminal. Taking the needle to set with  R6. 
- A repeat.
- B repeat.
- C: if there are differences with R18 compensate. If necessary repeat A+B.
- The TA End position is adjust with R13. The PC terminalss are open.
  No resistance is attached. The needle points to set.
  If necessary repeat C.
  
Sensitiveness
The sensitiveness is adjusted as described in a previous E mail.
This happend with the help of R22 Max and R17 Min. 

Function test
Attach 5000 ohms to the PC terminal, TA button keily points at 2, the needle on set, the sensitiveness points to 40 (Max). Turn the sensitiveness on zero now, the needle 
may himself for only +/-1 tic moving.

Questions to me, please.
