Frequently asked questions
Sisgeo digital instruments can operate in two powering modes: TIMED or ALWAYS-ON (for more information see F.A.Q.#094.A string of mixed instruments consisting of TIMED gauges and ALWAYS-ON gauges cannot work.The first thing to do is therefore to check that ALL connected instruments in your array are set to TIMED mode.You can check the powering mode […]

It could be a problem connected to the power supply given by the readout or logger. When the power supply is in the current loop (2-wire gauge) it is necessary to consider the effect of voltage drop across the shunt resistor on the voltage applied to the gauge. For example, suppose a 4-20mA gauge requires […]

The main factors which influence the anchor measurements are: – axial misalignment of the jack– difference in diameter between the jack and the load cell. These factors cause bending of the bearing plate between the load cell and the jack and affects the response of the cell. To minimise this effect use the genuine distribution […]
