4.6. HOLD, MAX/MIN/AVG, PEAK±
The following functions are available for measurements of AC and DC voltage, AC current,
frequency and resistance.
4.6.1. HOLD
The HOLD function permits to block on the display the detected value during
measurements of AC and DC voltage, AC and DC current, frequency and resistance. Just
press FUNC/HOLD for at least one second. The symbol HOLD is displayed. To escape
this function press again FUNC/HOLD or the arrow keys. This function is not available
when MAX/MIN/AVG or PEAK± functions are active.
4.6.2. MAX/MIN/AVG
During measurements of AC and DC voltage, AC and DC current, frequency and
resistance it’s possibile to measure and display the maximum (MAX), minimum (MIN) and
average (AVG) valus of the quantity under test. Press FUNC/HOLD for more than one
second to enter this function and press it repeatidly for less than one second to run
through MAX, MIN or AVG. The corresponding symbol is displayed. Maximum, minimum
and average values are detected since this function is activated and are continuously
updated even if not displayed. For example, while the AC current average value is
displayed, the maximum and minimum values of the same quantity are continuously
updated. To escape the MAX/MIN/AVG function press again FUNC/HOLD for more than
one second or the arrow keys.
The MAX/MIN/AVG function is not available when HOLD or PEAK± functions are active.
4.6.3. PEAK±
During measurements of AC and DC voltage and AC/DC current it’s possibile to measure
and display the maximum (PEAK+) and minimum (PEAK-) peak values of the quantity
under test with a resolution of 1ms. Press MODE/PEAK for more than one second to enter
this function and press it repeatidly for less than one second to run through PEAK+ or
PEAK-. The corresponding symbol is displayed.
Maximum and minimum peak values are detected since this function is activated and are
continuously updated even if not displayed. For example, while the maximum peak values
of AC current is displayed, the minimum peak value of the same quantity is continuously
updated.
When displaying maximum and minimum peaks it’s not mentioned whether the
corresponding quantity is AC or DC: a peak value is absolutely a peak value, regardless of
the quantity at which it’s detected. To escape this function press again MODE/PEAK for
more than one second or the arrow keys.
The HOLD and MAX/MIN/AVG functions are not available when when PEAK± is active.
