ERROR MESSAGES
Several error conditions may occur while using the
LC103 which cause an error message to appear in the
COMPONENT TEST RESULTS display. These are
usually caused by small errors in the operation of the
LC103, although severely defective components may
also cause certain error conditions. The error conditions
are explained below.
Component Type Selection Error
- This error occurs
when a component test is attempted, and either an
incorrect COMPONENT TYPE switch is selected for
the test, or no COMPONENT TYPE switch is selected
when required.
Possible causes:
1.
Performing a capacitor test with an inductor
COMPONENT TYPE switch selected.
2.
Performing an inductor test with a capacitor
COMPONENT TYPE switch selected.
3.
Performing the INDUCTOR RINGER test without an
inductor COMPONENT TYPE switch selected.
Entered Value Beyond Range of Unit
- The
component parameter entered via the keypad or RS-232
is beyond the measuring range of the LC103.
Possible causes:
1.
Entering a capacitance value greater than 19.9
Farads, or less than 1.0 picofarad.
2.
Entering an inductance value greater than 19.9
Henrys, or less than 0.1 microhenrys.
3.
Entering a leakage voltage greater than 1000 volts.
4.
Entering a tolerance percentage greater than +100%,
or less than -99%.
5.
Entering a tolerance percentage that includes a
decimal.
NOTE: Entering a leakage voltage less than 1 volt will
set the leakage supply to 0 volts.
Entered Value Beyond Range of Test
-The component
parameter entered via the keypad or RS-232 is beyond
the limits of the automatic GOOD/BAD test. The
component may still be able to be tested, but not for a
GOOD/BAD indication.
Possible causes:
1.
Performing an ESR test with a capacitor value of less
than 0.01 uF entered.
2.
Performing a D/A test with a capacitor value of less
than 0.01 uF entered.
3.
Performing an INDUCTOR RINGER test with a
inductor value of less than 10 uH entered.
Value Beyond Zeroing Limit
- The amount of
inductance or capacitance at the TEST LEAD INPUT is
beyond the range of the zeroing circuits. An open
(greater than 20 kohms) or shorted (less than 1 ohm) test
lead will cause the display to show “OPEN” or
“SHORT.”
Possible causes:
1.
The capacitance at the TEST LEAD input is greater
than 1800 pF.
2.
The inductance at the TEST LEAD input is greater
than 18 uH.
3.
The resistance at the TEST LEAD input is greater
than 5 ohms.
No Voltage Entered
- This error occurs when the
CAPACITOR LEAKAGE button is pushed and no test
voltage has been entered.
Invalid RS-232 Command
- An improper command
was sent to the LC103 via the computer interface.
Possible causes:
1.
Sending a command that is not recognized by the
LC103.
2.
Wrong command syntax.
NOTE: Refer to the COMPUTER INTERFACE section
of this manual for information on
using the ReZolver
with computer control.
Component Out Of Test Range
- The component
under test exceeds the limits of the test which was
attempted.
Possible causes:
1.
Measuring ESR of a capacitor having a value less
than 0.02 uF.
2.
Measuring capacitance value on an extremely leaky
capacitor.
3.
Attempting a capacitor value test with 1 ohm to 2
Megohms of resistance connected across test leads.
