• Price/Units Mode
As much as one wants to generalize, there
are invoices where price appears first then
the number of units. To facilitate this type of
invoice, again Monroe provides another
selectable format. This format accepts the
first entry as dollars and cents and the sec-
ond entry as a whole number.
• Price/Price Mode
Typical within the trucking industry, certain
invoices have fractional quantities (weight)
times price. Selecting yet another format to
simplify entry, the Monroe 8130X / 8145X sup-
ports price/price mode. In this format both
first and second entries are accepted as 2
decimal places automatically.
Clear Add Symbol
The 8130/8145 prints a unique symbol on the
tape called the clear add symbol if that entry
was the first entry made into a clear adding
machine. This symbol C+ clearly indicates to
the operator or anyone auditing the tape that
the adding machine was clear prior to com-
mencing the listing of figures.
Sequential Calculation Indicators
Special audit trail symbols are provided to indi-
cate to the operator when a chain or sequential
calculation is or has been performed. CX and C˜
illustrate a chain calculation is being performed.
These indicators are especially useful to insure
correctness of results and simplify audits of
results.
Calculator Mode Correction
How many times has one entered a figure,
pressed the times key instead of the divide key,
or vice versa. It happens often. Calculator
Mode correction is a feature that permits the
operator (in the sequence described above) to
immediately follow the times key depression
with a depression of the divide key. Doing so
changes the mode from multiplication to divi-
sion.
Entry Only Display
The Monroe 8130X / 8145X allows the operator a
choice of seeing the entry just made in the dis-
play or the running subtotal. Showing the entry
only in the display is clearly a superior audit
tool, as it enables the user to quickly check the
display when they feel an entry error has been
made. It is also an exclusive feature to Monroe
8130X / 8145X and our other heavy duty models.
Running Subtotal Display
The operator has the choice of seeing the entry
only or running subtotal in the display.
Automatic Constants
All Monroe calculators accept the first entry in
multiplication and the second entry in division
as an automatic constant. There are no K (con-
stant) switches to worry about or move. For
calculators with a K switch, one needs to worry
about engaging it first to perform calculations
with constants then disengage before adding a
column of figures. This is certainly contrary to
the goal of a calculator.
