4) When calculating relative value, press the REL /% key.
Note
The instrument can switch (select) reference resistance value when measuring
dBm.
The reference resistance value is switched as follows every time the RANGE
key is pressed. (Shown in sub-display.)
Reference resistance value:
4,8,16,32,50,75,93,110,125,135,150
200,250,300,500,600,800,900,1000,1200
Default value: 600Ω
● MIN/MAX/AVG Function
The minimum value (MIN), maximum value (MAX) and average value
(AVG) during measurement are shown. The average value is shown by
dividing the integrated record data by the number of recording times.
Pressing this key starts recording and at the same time the display shows
“MIN”, “MAX” and “AVG” to release AUTO POWER OFF.
<Recording time>
The timer is activated to show the elapsed time from the start and
simultaneously the renewed time for MIN/MAX is also recorded.
