logging of soil profiles and geological sections and exposures. It can be used either with the
upper section of the MS2 probe handle alone (the cable can be retracted and coiled up at the top
of the handle) or with the extension tube for ground level use.

11.2. Operating Instructions

11.2.1. Connecting the Probe to the Handle Electronics Unit
1. Inspect the 'O' ring seals on the handle and extension tube to ensure that they are in contact.
2. Correct connections are clearly marked on the electronics unit. Accidental direct connection
of a probe to the MS2 unit will result in excessive current drain, but will not cause permanent
damage. Connect the probe to the handle electronics module using the supplied 50Ω TNC-
TNC cable which passes up the inside of the tubular parts and emerges at the top of the
handle through a liquid tight gland.
3. If required, the cable can be retracted to facilitate connection of the probe to the top section
of the handle alone.
11.2.2. Taking Measurements
1. Switch on and allow a 10 minute warm-up time.
2. Select the x1 sensitivity range on the front panel of the MS2.
3. With the sensor at least 100 cm away from the material to be measured, press the 'Z' button
on the front panel of the MS2 to zero the instrument.
BARTINGTON INSTRUMENTS
The probe provides a series of comparable and repeatable
contact readings.
The value of the readings obtained will be approximately 0.5 c
with the sensor placed against a flat surface and 1 x c
buried up to the shoulder. See Figure 14 for the variation in
sensitivity around the MS2F probe head.
Note: The whole of the sensor end must be placed against a
flat surface for accurate readings.
