6.1 Button HOLD/REL

6.1.1 HOLD function

This function is used to 'freeze' the measurement result on the
display. To do this, shortly press HOLD/REL button. When the func-
tion is enabled, the display shows symbol HOLD.
To return to the normal operation mode of the device, press
HOLD/REL button again.

6.1.2 REL function

This mode enables a measurement relative to a reference value.
 To enable the mode, press and hold HOLD/REL. Then, the dis-
played readout value is taken as the reference value, and the
readout will be reset.
 From this moment, the readings will be presented as the ratio of
the measured value to the reference value.
 To enable the mode, press HOLD/REL.
The displayed main result is the difference between the reference
value (read-out at the moment of activating REL mode) and the cur-
rent read-out. Example: if the reference value is 20 A, and the cur-
rent reading is 12.5 A, then the main result on the display will be
-7.5 A. If the new reading is identical to the reference value, then
the result will be zero.
 When the function is activated, the automatic adjustment
of the measuring range is not available.
 If the reading is outside the measurement range, symbol
OL is displayed In this situation, turn off the function and
manually switch to a higher range.
 This function is not available for diode test.
