4. Enter setup data for measurement depth interval, drift warning level and auger hole
reference, and select SI/CGS and 1.0/0.1 range to match the meter settings.
5. Insert the probe into the test hole and allow time for probe temperature to settle. (See
Temperature Drift Effects
.)
6. Remove probe from hole, clean probe, and hold in air, clear of the ground and surrounding
objects. Click on OK to perform the first ‘air’ zero reading.
7. Insert the probe into the hole so that the lowest (sensing) graduation mark is at ground level
(i.e. depth = 0mm) and click Measure (or press F9) to perform a reading. Hold the probe
steady until the meter beeps to indicate that the reading has been taken.
8. Lower the probe by the desired reading depth interval (using the graduated depth scale on
the probe/tube) and click Measure to take the next reading. Continue this process until all
readings to the desired depth have been recorded. Readings can also be taken as the probe is
extracted from the hole.
9. Click on Apply Corrections. You will be prompted to remove the probe from the hole, clean it,
and perform another ‘air’ zero reading. The software will then automatically calculate zero
drift over the time of the measurement run and apply corrections based on the time of each
reading (a linear zero drift with time is assumed).
10. Data can be saved to file and/or plotted (see Multisus manual for details).
13.3.3.4. Using the MS2H Probe Without a PC
It is possible to use the probe and meter without a PC, but all readings must be made and zero
drift corrections applied by hand, as there is no logging facility within the MS2 meter.
The procedure is as follows.
1. Follow the procedure above to assemble the probe and connect to the meter.
2. Select SI or CGS and 1.0 range on the meter.
Note:
For the MS2H probe, the 0.1 range is not recommended.
3. Insert the probe into the test hole and allow time for probe temperature to settle.

4. Remove probe from hole, clean probe, and hold in air clear of the ground and surrounding
objects. Press the 'Z' button to zero the instrument.
