Recording the crest current readings: RECORD PEAK
This mode enables detection of the absolute value of the crest current with a response time
of less than 2 ms.
Recording frequency: RECORD Hz
In RECORD Hz mode, there is no RECORD PEAK mode. Each press of the PEAK/SMOOTH
button changes the mode: either RECORD SMOOTH giving an average value over 3 seconds,
or normal recording of frequency readings with a response time depending on the frequency
of the signal to be measured.
Displaying readings
In RECORD mode "100 ms" or "SMOOTH" (in Amps or Hz) :
On the bargraph:
When measuring current, the MAX and MIN recorded are displayed on the bargraph by
a flashing segment indicating their values. When measuring frequency, the bargraph
still indicates the instantaneous current value.
On the digital display:
Each press on the MIN/MAX button (Clamp F3N) switches the display between MAX, MIN,
AVG and the present value, the bargraph continuously and instantaneously displaying
the present current value with a response time of 100 ms (on amps or frequency).
On RECORD PEAK mode (only on Amps):
During recording, the crest reading over a 100 ms cycle is still displayed on the bargraph.
On the digital display it is possible to display:
- The average of 4 peak readings (read over 400 ms);
- The MAX reading of PEAK (the highest of the instantaneous peak values).
Each press on the MIN/MAX button switches round the display of these readings.
The MAX reading is displayed on the bargraph by a flashing segment.
HOLD RECORD function
On RECORD mode, a press on the HOLD button temporarily stops RECORD mode
(the symbol H
The data recorded is maintained and held, it can be read on the display.
In normal or SMOOTH mode (amps or frequency), the present, MAX, MIN or AVG
readings are displayed by successive presses on the MIN/MAX button.
On PEAK mode (amps), after a press on the HOLD button, presses on the MIN/MAX
button switch between the display of the readings: PEAK MAX, present PEAK reading
and HOLD reading. This HOLD reading is the current or frequency reading which was
present when the HOLD button was pressed.
Remark : Pressing HOLD again enables recording to continue without the need to reinitalise
previously recorded readings (MAX, MIN, AVG or MAX of PEAK).
