OPERATION

Getting Started, a Tutorial

Confidence Check – Three steps to get going —

If you received this instrument directly from the factory, a battery was included but not
installed, memory was cleared and default settings are effective. The following will
familiarize you with your new Ionizer Performance Analyzer Model IPA 287a:

1) Install battery

a) Remove the two crosspoint screws from the battery compartment cover.

b) Carefully lift the cover off of the compartment.

c) Insert the battery, refer to label for orientation.

d) Replace the cover.

2) Demonstrate basic functions. Pressing a single button and releasing within two seconds

controls basic functions.

a) Press and release ‘ON-OFF’. The display will briefly show information about the

instrument and then the battery voltage. A low battery condition will present an error
message.

The main menu startup screen will show a blank voltage, memory usage status,
relative humidity, present temperature and battery voltage.
NOTE — If the instrument has been used it may display the option of clearing the
memory. Do so by scrolling to “Y” with

 or  key then press ‘ENTER’.

b) Press and release ‘AUTO’. This will start the first automatic test sequence:

The instrument performs an autozero.

ii)

The floating plate is charged to >+1050 volts.

iii)

The plate begins to discharge. If allowed to discharge to <+1000
volts the timer will start at +1000 volts.

iv)

This test is the first automatic decay test. The first test in an
automatic sequence is always positive. The test is labeled ‘11+’
(Automatic Test Sequence 1, Test Number 1 [in a sequence of 6
tests], and the test voltage is + [positive]).

Abort this test by pressing the ‘AUTO’ button again (‘CANCEL’).
