In Zero mode, the instrument stores the last reading (at the time of Zero key press) and subtracts it
from all subsequent readings. It continues to do this until it is either cancelled (by pressing the Zero
key again) or until power is removed.
Zero mode also works on differential measurements (A – B). In this case, both channels values are
frozen at the time the key is pressed. The absolute value, in the example above, is replaced by the
relative difference value.
To cancel the relative measurement mode, press the Zero ( 0 ) key again. Zero mode is cancelled
when power is turned off.
4.1.2.3 Selecting run/hold mode ( )
Instrument measurements stop completely when Hold mode is active. This is indicated on the bottom-
left of the display where Hold mode indication alternates with the current conversion method,
providing a flashing indication. Hold mode may be used when the F100 is in differential mode.
Press the Hold ( ) key to alternate between run and hold modes. Hold mode is cancelled when
power is turned off.
