c) Press and release ‘+ CHARGE’. This will start a manual test where the test voltage

is positive.

(i) 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 is a single positive manual decay test. The test is labeled ‘

M1+’

(

Manual, Test 1, + [positive]).

Abort this test by pressing the ‘CANCEL’ button.

d) Use the ‘

 CHARGE’ button similarly to perform negative manual decay tests. Up to

ten manual decay tests may be run in any polarity order. The ten tests will be

labeled

1 thru 0 with the polarity indicated. Thus, the 5

test might be labeled ‘M5’.

3) Shut the instrument off (press and release ‘ON-OFF’). You will need at least an ionizer

and a ground connection to proceed.

Further familiarization —

In order to become more familiar with the accumulation and presentation of data we will

perform two automatic test sequences and a few manual tests and then examine the results:

1. Set up the ionizer.

2. Ground the IPA 287a. A ground jack is provided on the side of the instrument case.

3. Access the main menu. The display should show 0% values for A

utomatic and

anual memory usage.

If a message prompts you to

ClrData (clear data),

a) Scroll to ‘Y’ with either the

 or  button.

b) Accept this by pressing ‘ENTER’.

4. Run an automatic test sequence —

a) Press ‘AUTO’.

b) Let the test run its course. This is ‘

Test 1’.

i) Six decay tests are run. These are in the order +++

 or +++

depending on the current autosequence setup.

ii) A balance test is run. The duration of the balance test may be any value

between 10 and 90 seconds or it may be turned off in the SETUP menu.
