6.2 Probe zero

The next step is to perform a probe zero. The zero function is a very important and necessary function that must be done prior to calibration. It should be done on a regular basis. In fact, the CMX has been programmed to force this issue at regular intervals during operation if it hasn’t been done. If the CMX is not zeroed correctly, all the measurements taken may be in error by some fixed value. When the CMX is using the auto zero (electronic zero), the CMXDL can be in any measurement mode. However, when the manual zero is being used, the CMX must be in pulse-echo mode in order to perform the zero. The CMX will also see to it that this occurs by simply forcing the gauge into this mode when zero. Therefore, if the CMX is in the echo - echo measurement mode and a manual zero is being performed, the CMX will put the gauge into pulse-echo mode automatically before performing the zero. While this is a very convenient feature of the CMX, the user should be sure to check the measurement mode following calibration to be sure the CMX is in the desired mode. The following steps outline both of these techniques.

The CMX is equipped with two zero options:

1)Off Block Zero (Automatic Probe Zero) – When this feature is enabled the CMX will do an electronic zero automatically, eliminating the need for a zero disk or block.

2)On Block Zero (Manual Probe Zero) – When this feature is enabled the transducer must be placed on the probe zero disk (battery cover located on the top of the unit.

Both zero procedures are outlined as follows:
