The ROUTE Module
Hints for Efficient Data Collection
If you have already saved data for the POINT, averaged data can be erased at any time
and the averaging process restarted from zero by simply taking data for the same
POINT again. When you save the new measurement, you will be prompted to either
Append, Overwrite, or Discard the measurement (depending on the Hist. Data Collect
setting in Configuration). Select Overwrite to replace the last measurement.
In most instances, magnetic coupling to the structure is used.
Data collected with hand-held probes are affected by the angular
orientation and pressure provided by the user.
The GX Series Microlog indicates auto-ranging prior to collecting
data. The collection display does not indicate the current average
number.
When disconnecting the sensor connector from the CH
connectors, ensure the red dots are aligned, grasp the sensor
near the sensor tip and pull gently (do not twist).

Input Range
The GX Series Microlog reports input signals too large for the display with an Input
Overrange banner on the plot. If a signal overload is indicated, the full-scale amplitude
increases to prevent amplitude errors, and data is collected.
Bias Check
Within the ROUTE hierarchy, press Shift+B to check the bias voltage for ICP
measurements. This turns on the ICP supply (if it wasn't already) and measures the DC
bias voltage for each channel used by this measurement (CH1 for single channel
POINTs, typically CH1 and CH2 for two-channel POINTs, and CH1, CH2, and CH3 for
Triax POINTs). A Bias check results screen displays.
This screen shows the voltage(s) for each channel, along with a red / green indication:
green if the bias voltage is between 2 V and 18 V, which is regarded as normal, and red
if it is outside this range.
This can be useful to troubleshoot a potential cable or accelerometer problem.
