2.5.6 DISPLAY / SMOOTH Button
DISPLAY
The DISPLAY function switches between accessible results depending on the
main rotary switch position. The information displayed depends on the state of the
instrument:
State 1: before a measurement starts
State 2: during a functional measurement
State 3: after a functional measurement
In all Functions except SET-UP:
External voltage measurement is possible in State 1 and 3. The external voltage
measurement runs permanently if the DISPLAY button is pushed. The values are
always indicated in the small numeric displays (A2 and A3, see § 2.4) while the
main numeric display is empty.
SMOOTH
To get a more stable display result, it is possible to smooth the measurement
by pushing and holding down the
button, then the SMOOTH button during a
measurement. Display results last until the SMOOTH button is pressed again.
2.5.7 Hz /OPTIONS / DISTANCE Button
Hz /OPTIONS
This button enables selection of parameters that are used in different functions.
Depending on the state (see § 2.5.6 above) of the instrument, this button option
has different functions.
In State 1 and 3:
• AUTO / MANUAL mode
• Test frequency
• Test voltage
• Current direction (polarity) in Bond Resistance/Continuity Measurement
Pushing this button causes the associated symbol to blink. Modifications can be
performed with the arrow buttons. Previously measured results are lost if any parameter that influences the measurement result is altered.
In State 2:
During the measurement in MANUAL mode, the Hz/OPTIONS button directly
enables the modification of frequency (in 3-Pole and Resistivity Measurements), or the current direction (polarity) in Bond Resistance/Continuity Measurement.
