during edit. The reference default value of 10000 (decimal point determined by range) can be
entered by pressing Clr and the latest meter reading can be entered by pressing Copy rdg.
Limits
High and low limits can be set, against which the current reading is compared. When running, the
main display shows the actual reading and the secondary display shows PASS (reading between
or equal to set points), HI (reading >HI) or LO (reading <LO).
Having selected Limits from the modifier menu with the FUNCTION key (LIMITS symbol flashing),
pressing Edit will permit the HI and LO limits to be set in turn using the Change Digit, Step Digit
and +/- keys as previously described in the Number Editing section. HI or LO will show in the
main display during edit, as appropriate. The units and decimal point position are set by the
current meter range which must be selected before the modifier is selected and editing begins. If
the value and resolution of the set points requires two different ranges to be used to set the
values it will be necessary to exit the edit mode and modifier after setting the first limit so that the
range can be changed for the second limit.
The limits can be set anywhere in the range ±00000 to ±99999 with the decimal point set by the
range selected during editing. Pressing Clr enters the default value of +00000; pressing Copy rdg
enters the current reading.
Min-Max
This modifier stores the maximum (most positive) and minimum (most negative) values that occur
when the modifier is run and displays one or other in the secondary display simultaneously with
the current measurement in the main display.
To select Min-Max, press the FUNCTION key until the Min Max symbols flash in the menu of
modifiers. Pressing Run will initiate the function and display the minimum value in the secondary
display, indicated by the Min symbol only now showing. Further presses of Run will alternate the
secondary display between Min and Max.
Min and Max are stored as floating point numbers and the modifier can be operated with the
meter changing ranges either manually or by autorange.
To reset the current min or max without exiting the function, select Min or Max with alternate
presses of the Run key and press Edit.
Changing function cancels Min-Max.
Ax + b
When running, the scaled value (Ax + b) is shown in the secondary display and the normal value
(x) is shown in the main display. If the scaled reading exceeds ±99999, -Or- is shown in the
secondary display to indicate over-range.
To select Ax + b press the FUNCTION key until the Ax + b symbol flashes in the menu of
modifiers; pressing Edit will then permit the two parameters, A and b, to be set as described
earlier in the Number Editing section; A or b will show in the main display during edit, as
appropriate. A is variable from ±0.0001 to ±9.9999, with the decimal point in a fixed positon after
the first digit; the default value is 1.0000, entered by pressing Clr. b is a floating point number
variable over the range ±00000 to ±99999 with the decimal point and units set by the range
selected during editing; the default value is zero, entered by pressing Clr, and the current
measurement value can be entered as b by pressing Copy rdg.
