32.0 TROUBLESHOOTING - DISPLAY MESSAGES AND TROUBLESHOOTING GUIDE
A flashing alpha-numeric message in the display generally indicates an incorrect combination of jumpers and/or
configuration values.
32.1 Error Mode Messages
32.1.1 Flashing “999999” (Numerical Overflow)
The maximum number of counts in the display cannot exceed -99999 or 999999. If, by moving the ACTIVE decimal point
one or more places to the left, you cause the display to move beyond the maximum number of counts it is capable of
showing (for example, 12345.0 to 12345.00), the display will indicate the overflow by flashing
“999999”.
32.1.2 Flashing “ERR 01” (Offset Overflow)
When an offset value has been entered and then the ACTIVE decimal point has been moved one or more places to the
left, causing the offset display reading to move beyond the maximum number of counts it is capable of showing (for
example, 1000.00 to 1000.000), the display will go into offset overflow.
The meter will only display 6 digits (999999) maximum.
32.1.3 Flashing “ERR 02” (Setpoint Overflow)
After a Setpoint (or Alarm) value has been entered and then the ACTIVE decimal point has been moved one or more
places to the left, causing the setpoint display reading to move beyond the number of counts it is capable of showing (for
example, setpoint at 100.00 and then a decimal point change to 100.0000), the display will indicate the SETPOINT
OVERFLOW by momentarily flashing “ERR 02” before returning to the run mode.
The meter will only display 6 digits (999999) maximum.
32.1.4 “NOSTOR” and “STORED” (Programming Entries In EEPROM)
If you are in the configuration mode and you make a CHANGE to any setup parameter and press the ‘RESET’ button, the
display will MOMENTARILY flash either “STORED” or “NOSTOR” and then go to the next menu item.
32.1.5 Flashing “OVLD” (Positive Input Overload)
If the input signal exceeds the range selected (for example, 0-100 mV range selected and greater than 200 mV is applied
to the input), the display will flash a “+OVLD”.
32.1.6 Flashing “OPEN” (Open Sensor Indication)
Coupled with the proper jumper selection, the display will indicate an open sensor.
32.1.7 Flashing “-OPEN” (Open Sensor Indication)
Coupled with the proper jumper selection, a “-OPEN” indicates the input is below the bottom limit of the range selected.
32.1.8 Flashing “I OVSC” (Input Overscale)
This display occurs when the input scale and/or offset applied to the input signal causes the display to go into a numerical
overflow.
