Helpful Hints
■
The most commonly used formulas are indicated by an asterisk.
■
The values for “X,” “Y” and “Z” are taken in descending order. For example,
the value for “X” is greater than the value for “Y”
■
The values are for successive singular harmonic images. Do not use
multiple images.
■
If two points are recorded, equation (1 Y gives only approximate results.
Equations (2) with (4) and (3) with (5) are more precise, but error can be
introduced due to the rounding.
■
If three points are found, Equation (6) is the most commonly-used formula.
■
For completeness, equations (9) through (21) offer mathematical derivations
and condensed versions of Equation (6). Also included are the formulas for
calculating Sx, Sy and Sz.
Battery Charger Setup
When first using the battery charger, select
the appropriate plug connector for use in the
AC power outlet (several styles provided)
and align the holes in the rear side of the
plug connector “C” with the pins in the
receptacle in the battery charger body “D”
and push. When properly seated, you will
hear a click and the plug connector will not
move. The charger is now ready for use.
To Change the Plug Connector
To remove the connector from the battery
charger, slide the switch on the battery
charger “E” up and the connector will pop
out. To insert a different plug connector
follow the procedures described in Battery
Charger Setup.
Charge the battery before first use or when
the “LOW BAT’ indicator shown in LCD is
illuminated.
NOTE:
When the “LOW BAT” indicator is
shown, the PK2 has approximately four
minutes of operating time remaining. When
the “LOW BAT” indicator flashes on and off, the battery is emply and the PK2 will
automatically switch off.
Before first use, you must set up the battery charger. Refer to Battery Charger Setup
shown below.
1. Insert the barrel plug end of the battery charger (
A
) into the
Battery Charger Jack on the PK2 (see callout H on page 4). Plug the charger into a
wall outlet.
■
The red light on the charger will shine continuously while the battery is
charging.
■
The red light will flash when the battery is fully charged. The instrument will
recharge in about two hours (three hours maximum).
