Extras — for other functions,
plus a function for displaying the
Min/Max values.
Measuring the Min/Max values has a special
significance and is explained in more detail
below.
Apart from the current measured values, the
HMG records the minimum and maximum
values (Min/Max values) too, except when
plotting a measurement curve. The minimum
value is the lowest value to which a meas-
ured variable has dropped during the time
period under consideration, the maximum
value being the highest value achieved by a
measured variable during this period. Reset-
ting causes the Min/Max values to be set to
the actual measured value at the time. This
will reset all sensors.
The time period always begins when the
Min/Max values are reset. The values are
reset in the following situations:
• Switching the unit on
• Selecting and activating Reset function in
the menu bar
(only if Min/Max is active)
• Connecting or removing an HSI sensor
• Altering the sensor settings
• While recording an event log
• When finishing recording
Before resetting the Min/Max values it is fre-
quently necessary to determine when the
Min/Max values were last reset. To do this, go
to Extras in the function bar and then About
HMG 3010.
Note:
Even when the Min/Max values
are not shown in the display,
the HMG is nevertheless re-
cording them in the back-
ground.
