CHANNEL - the measurement channel
PROBE - the ID of the probe
TIME REMAINING - the amount of time left to complete the zero-power sequence of measurements in
minutes and seconds (00:00)
STEP - indicates the current measurement step of the sequence
SENSING CURRENT - the sensing current implemented in the measurement step
PHASE - indicates whether measurement is in SETTLING or MEASURING mode
MEAN - the arithmetic mean of the measurements taken in the current step
STD DEV - the standard deviation of the measurements used to calculate the mean
CANCEL (F1) - terminates the zero-power measurement sequence
Once the Zero-Power Measurement sequence is complete, the following results are reported on the screen.
DATE - the date of the measurement
TIME - the time when the measurement nished
CHANNEL - the channel measured
PROBE - the ID of the probe conguration
ZERO-POWER RESULT - the calculated zero-power value
SELF-HEATING - the amount the probe measurement changes due to self-heating
STANDARD ERROR - the resulting standard error of the mean of the zero-power result
DRIFT - indicates the difference between the nominal current measurements (applies only if Repeat Nominal
is enabled)
SENSING CURRENT 1 - the measurement current used in the rst step of the sequence
MEAN 1 - the mean of the measurements in the rst step
STD DEV 1 - the standard deviation of the measurements in the rst step
SENSING CURRENT 2 - the measurement current used in the second step of the sequence
MEAN 2 - the mean of the measurements in the second step
STD DEV 2 - the standard deviation of the measurements in the second step
(the following apply if Repeat Nominal is enabled)
SENSING CURRENT 3 - the measurement current used in the third step of the sequence
MEAN 3 - the mean of the measurements in the third step
STD DEV 3 - the standard deviation of the measurements in the third step
The measurement results can be written to memory by pressing the WRITE FILE (F1) function key. The user
may change the le name by pressing the ENTER key and using the alpha-numeric interface. Once the le
name is set, and after the USB memory device is inserted into the front USB port, the user presses the CON-
TINUE (F1) function key to proceed to write the le. The le is stored in a folder named “\159x\zero”. If the
le already exists, the new test results are added to the le.
The results of the zero-power measurement are written to the le as follows:
DATE,<date>
TIME,<time>
CHAN,<channel number>
