Multi Conversion
kFirst, check the current conversion rate.*5
Am(RATE)
kTo set the conversion rate
Example: To assign a euro value to Value 2 and a dollar value to
Value 1 to set up the conversion rate below*5
1 euro = $1.1 US
1. A
2. Hold down %(SET) until “SET” appears on the display.
3. m(RATE) ... This causes the following to appear: “VALUE2”,
“SET”, “RATE”.
4. 1.1
%(SET) ... Input the correct conversion rate (such as 1 euro =
$1.1 US).*6
*5For Value 2, specify the conversion rate to be applied to Value 1.
*6For an conversion rate of 1 or greater, you can input up to six
digits.
Example: 123.456, 1.23456
For a conversion rate that is less than 1, you can input up to 12
digits. Note, however, that you can input only six digits to the right
of the decimal point or to the right of any leading zeros in the
decimal part.
Example: 0.123456, 0.0123456
• The conversion rate is not cleared if you press Aor if you turn off
the calculator.
