On power up, the UPR700 will enter a self-test mode to evaluate the condition of the equipment. If
an error is detected, the screen will show an error code number in the upper display and the
mnemonic
Err
, in the lower display.

ROUBLESHOOTING
The errors codes and their possible causes and solutions are as follows:
1
Error during EEPROM access.
Correction:
De-power the instrument and wait for 60 seconds. On power-on the situation
should clear itself. If it does not correct itself de-power again. If the error still remains, send
the instrument to Dynisco for repair (See Section 13).
3
Wrong zero measure.
Correction:
Check that the wiring is correct. Check that there is NO pressure applied on the
transducer. If there is no pressure on the transducer, and the wiring is correct, contact
Dynisco Technical Assistance at 800-221-2201.
5
Input calibration error.
Correction:
Check that there is no pressure applied to the transducer. If the transducer is at
zero pressure, verify that the SHUNT is turned on, and the Jumpers are set correctly. Also
verify that the wiring is correct, especially that the Orange wire is on Terminal 14, and the
Blue wire is on Terminal 17 with the Green wire. Disconnect the transducer from the
wiring, and either replace the wire, or check the continuity of EACH wire, and that there is
no short between any of the wires. If the cable is good, substitute a known good transducer
to determine if the transducer is damaged. If the good transducer shows the same error,
send the instrument to Dynisco for repair (See Section 13).
6
Wrong Reference Junction Measure.
Correction:
The on-board thermocouple cold reference junction was read improperly. Press
RESET to try to clear. If this does not work, turn the instrument off, wait about a minute, and
turn the power back on. Verify that the instrument is not outside its operating temperature (-
20 to 60
°
C). If the error persists, send the instrument to Dynisco for repair (See Section 13).
11
Overload or short-circuit on strain gage power supply, or unconnected “-4-EXC” or “-EXC”
wire.
