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 133 (3-channel) signal conditioner?
Answer
The calibration process is a ""Special"" mode function and is initiated by pressing the < Select Function > push button while simultaneously pressing the < Left > and < Right > EDITS push buttons. Refer to page 1
Model 133, which has selectable IEPE current limits of: 0, 4 and 10 mA. I have an application that requires a longer cable length and a higher bandwidth, which can only be met with an IEPE current level of 18 to 20 mA. Is there a modification that can be made to the Model 133 to accomplish a higher
model 133 uses is pC (pico-coulombs) when configured as a charge amplifier, and mV when configured as an ISOTRON (IEPE type) amplifier. The 136 only uses mV. So, for example, when programming the input sensitivity for a charge accelerometer, the 133 will display pC/EU (where EU is engineering unit).
s the 133 can be used with both IEPE and charge mode accelerometers. The caveat is that the 133 is a single-ended conditioner, designed for use with single-ended accelerometers. Piezoelectric charge mode accelerometers are available in single-ended and differential output. The 133 does not work with
model 133 is connected to J1. The AC signal is rectified by the diode D1, allowing the positive swing to pass thru while blocking the negative swing. R1 serves as the isolation resistor between the model 133 output and the rectifier circuit. C1 is the filter capacitor and R2 is the discharge path. T
model 133 is available. The 133 provides three channels of IEPE signal conditioning in one package, and offers a lot of flexibility in accelerometer choices and output scaling for downstream data acquisition systems.

devco 133 and 136 signal conditioners are designed for ease of entry of the accelerometer sensitivity and the desired output specified in millivolts per engineering unit. In cases where very low sensitivity transducers are used, such as high g shock accelerometers the user must either round off the
model 133. While a typical test will probably be a transient event, the square wave is an effective test of rise time and the effects of high frequency bandwidth limitations. (repetition rate).
