4. Before reinserting the Signal Conditioner  
body into the case, the following must be  
checked :  
-The front label (blue color) must be in its correct position, with terminals 1 and  
7 (power supply) separated from the other terminals.  
-The three internal modules must be inserted correctly in their internal case  
guides.

OVERVIEW  
This module contains all the components for the frequency generator, and the trimmer for the  
Span coarse frequency, The jumpers and solder pads to select the output range frequency and  
solder pad to select the pulse width.  
Both models are delivered as a standard version, with the frequency output adjusted from 0 to  
4 KHz., unless specified otherwise.  
The frequency range can be set in pulses per second (12 different ranges, see table 2) or in  
pulses per hour (13 different ranges, see table 3), using the jumpers and solder pads located  
on the MS-55 module, see figure 5.

SIGNAL INPUT, module ME  
OVERVIEW  
This module together with the "MP" input board, performs all the input signal conditioning (see  
Fig. 2). This module contains the trimmers and jumpers for the amplifier gain and the low level  
output (offset).  
The signal input connections are made at Terminals 3, 4, 5 and 6.  
Each model may use some of these terminals, see the Connections Section.

until the reading of the voltmeter is 0.  
9. Adjust the calibrator until it generates the high signal level.  
10. Check the voltmeter reading is 10.0 V. If not, turn the trimmer P2, located on the "ME" input  
module, until the reading of the voltmeter is 10.0 V.  
11. Repeat steps 7 thru 10, until the two values are correct.  
12. Connect a digital frequency meter, to the signal output terminals 11 and 12. The reading must
