How to translate error codes for Endevco models 133 and 136
How do I program the gain on Endevco model 133 and 136 signal conditioners?
Model 136 when driving long cables. The test was performed using the following equipment:
Function Generator
Two Channel Oscilloscope
True RMS Voltmeter
Capacitance Decade Box
50 feet (15 meters) of RG-58 Coaxial cable
Endevco Model 136 Bridge Amplif
33 or 136 signal conditioner, particularly when trying to program the “gain†of the amplifier. However, armed with a few simple rules and some basic knowledge of these popular signal conditioners, it becomes really quite simple.
The most basic rule, but perhaps the most misunderstood,
model 136 Signal Conditioner and I am using a transducer that has a very low sensitivity of 2.847 microvolts per g. I am trying to enter this number into the output scaling of the 136, but I see I have to round it to 3 microvolts per g. It there a way I can enter the precise value?

Yes. The
f the 136 amplifier. Note that the shield from the 3907 interface cable is not connected to the accelerometer, but the shield wire should be connected to pin 9 of the 136 input connector to provide shielding for the cable. Pins 1 and 7 and pins 6 and 8 are jumpered at the 9-pin D connector, for chan

Answer
The low-pass filter (LPF) of a model 136, a 3-channel differential voltage amplifier, can be changed in the field by following these instructions.
