2.4.3 Digital I/O Port
See section 3.5.5 for features of the digital I/O port.
2.4.4 Probe Input
Connector
This section describes the probe input connection and pin-out details.
The Lake Shore Hall probe plugs into the 26-pin mini D-sub socket on the rear panel.
Align the probe connector with the probe input socket and push straight in. The con-
nector is push-to-lock. You should hear a clicking sound if the connector is fully
seated.
An electrically erasable programmable read only memory (EEPROM chip) is included
in each probe. The EEPROM chip stores specific information that the teslameter
requires for operation. The information includes serial number, probe sensitivity, field
compensation data, temperature compensation data, and calibration data. When a
new probe is connected, the instrument reads parameters from probe memory and
the probe is ready to use. A new probe can be connected at any time even while the
instrument is turned on.
2.4.4.1 Probe Handling
To avoid damage and for best results during use, probes have a number of handling
and accuracy requirements that must be observed.
Some probes used with the teslameter have conductive parts. Never probe near exposed
live voltage. Personal injury and damage to the instrument may result.
Force should never be applied to the tip of the probe. On all probes, do not pinch or
allow cables to be struck by any heavy or sharp object. Damaged or severed cables
may be returned to Lake Shore for repair but probes are not always repairable.
The cardboard and foam container that Lake Shore probes are shipped in should be
retained for probe storage and for return shipping for periodic probe recalibration.
For additional probe details, please see section 3.6.
