32.1.9 Flashing “R OVSC” (Reading Overscale)
This display occurs when the reading scale and/or offset applied to the input signal causes the display to go into a
numerical overflow.
32.1.10 Flashing “CB OVF” (Count By Overflow)
When a display value near the maximum display capability is forced into a numerical overflow by changing the CNT BY
menu (for example, the display reads 999997 and the count by is changed from 001 to 005 and rounds the display up to
1000000).
32.1.11 Flashing “UOM.OVF” (Unit Of Measure Overflow)
If a unit of measure is selected and you are near the full scale capability of the display and in the ACTIVE decimal mode,
the display will shift one digit to the left (for example, to a display of 1065.33 you add a unit of measure such as “F” for a
display of 1065.33F), the display will flash “UOM.OVF”.
32.1.12 Flashing “dP OVF” (Decimal Point Overflow)
If number of Decimal Points Setup was improperly configured.
32.2 Troubleshooting Guide
“99999”
POSSIBLE CAUSE:
TO CORRECT:
Active decimal point change driving the display into numerical overload.
Check the decimal point and set the required decimal point.
“ERR 01”
POSSIBLE CAUSE:
TO CORRECT:
Active decimal in “RDG.CNF > DEC.PT > DP.ACTV“has been selected and/or DEC PT
(decimal point) position has been moved one or more places to the left driving the
programmed offset value into numerical overflow.
Check the decimal point and set the required decimal point.
Alternately, the amount of RDG.OF may be reduced to get the decimal point further to the left.
“ERR 02”
POSSIBLE CAUSE:
TO CORRECT:
Active decimal has been selected and/or DEC PT (decimal point) position has been moved
one or more places to the left driving the programmed Setpoint value into numerical overflow.
Display will flash “ERR 02” message for a short period of time, then automatically correct the
setpoint’s decimal point position and move to the next menu item. Press the ‘SETPT’ button
until the meter displays flashing “999999”. Then press the ‘MAX’ button to reset the display to
“000000” and enter a new valid setpoint value.
“OVLD”
POSSIBLE CAUSE:
TO CORRECT:
POSSIBLE CAUSE:
TO CORRECT:
The positive input CURRENT & VOLTAGE exceeds the input range selected.
Check both the input range and the actual input to find the error condition and either reduce
the input or change jumpers to a higher input range for more input attenuation.
In the LINEAR (RTD) mode, input signal exceeds 690 ohms or jumpers S1-A,B or S1-C,D or
S1-E,F are installed and the input signal exceeds 6900 ohms. (Place the active decimal point
all the way to the right side: “FFFFFF.”).
Check both the input range and the actual input to find the error condition. To correct, either
reduce the input or change jumpers to a higher input range for input attenuation.
“-OVLD”
POSSIBLE CAUSE:
TO CORRECT:
The negative input voltage exceeds the input range selected.
Check both the input range and the actual input to find the error condition and either reduce
the input or change jumpers to a higher input range for more input attenuation.
“OPEN”
POSSIBLE CAUSE:
TO CORRECT:
Input sensor is open or broken, or the connection to the meter is open or broken. Input sensor
is not wired to the proper input terminals.
Check thermocouple or RTD wiring.
“-OPEN”
POSSIBLE CAUSE:
TO CORRECT:
The input sensor is open or broken, or the connection to the meter is open or broken. The
input sensor is not wired to the proper input terminals. The input signal is below the minimum
specified (refer to Section 33, Specifications).
When jumper S2-E on the signal input board is used, this will be indicated if a sensor lead is
