7.4 Connect a probe
Do not discard the probe connector port caps. Make sure that the probe connector port caps are installed when
no probe is connected.
Make sure that the display shows the current time and date and then plug the probe into the meter.
Refer to Figure 8.
Note: The time stamp for a probe is set when the probe is first connected to the meter. This time stamp makes it
possible to record the probe history and record the time when measurements are made.
