The HMO series includes five mathematical formula sets. Each
of these formula sets contains five formulas which may be edited
with a
formula editor to also define linked
mathematical func
-
tions. These are labeled MA1 to MA5. You can use the
universal
knob to select the formula set. The formula set editor (soft menu
key EDIT FORMULARY) lists all existing equations which may
be edited. A blue bar indicates that an equation is selected. It is
important to distinguish between editing the display and editing
the parameters. Use the universal knob to select the respective
equation and activate it by pressing the soft menu key
VISIBLE
.
An activated, visible equation is marked by a filled-in eye symbol
in the formula editor and is listed in the short menu.
In the soft menu
UNIT
you can use the universal knob to select
from the following units:
– V (Volt)
– A (Ampere)
– Ω
(Ohm)
– V/A (Volt per Ampere)
– W (Watt)
– VA (Volt Ampere)

multiplication (MUL) or division (DIV). Pressing the MENU key in
the VERTICAL control panel will switch you to a more detailed
display of the QM menu. You can use the
universal knob to select
operands and operators.

The formula editor menu (soft menu key MA) allows you to
activate and deactivate mathematical equations that are de
-
fined and displayed within the selected formula set. The list
only includes visible equations. Four out of five functions from
the current formula set can be displayed simultaneously. The
5th curve may be used as operand for one of the four math
-
ematical curves. It will be calculated, but will not be included
in the display. The MENU key in the VERTICAL control panel
opens a menu to select the formula set and its corresponding
formulas. You can also choose a NAME with a maximum of
8 characters, load a formula set (from the internal memory
or from a USB stick) or save a formula set (internally or on a
USB stick). You can use the
universal knob to enter the name
of your choice and you can save it by using the
ACCEPT
key. The
name will now be displayed Instead of the generic labels MA1…
MA5. You can specify the names for all equations separately.
Once all equations, constants and names have been entered,
you may also choose a name for this formula set by pressing
the
NAME
key in the formula set menu and entering the name
of your choice.

The unit selected for the equation will be applied to the channel
description, cursor types and
automatic measurement types.
The equation name is listed in the formula set editor and is
used as label in the curve window. The soft menu key DELETE
removes the equation from the formula set.
