Chapter 2. Error Codes

2.1 Introduction

Introduction to the error code system for troubleshooting.

E0: No Error

Indicates no current error condition, often a confirmation message.

E1: Low Signal

Problem with ultrasonic signal strength or exceeding programmed limits.

E2: Sound Speed Error

Sound speed exceeds programmed limits, potentially due to programming or conditions.

E3: Velocity Range

Velocity exceeds programmed limits, possibly due to data or flow conditions.

E4: Signal Quality

Signal quality is outside programmed limits, often due to flowcell or electrical issues.

E5: Amplitude Error

Signal amplitude exceeds programmed limits, possibly due to gas or particulates.

E6: Cycle Skip, Accel.

Acceleration exceeds programmed limits, often due to flow or alignment issues.

E7: Analog Out Error

Current in analog output circuit exceeds port limits, often due to load issues.

E8: Temperature In

Indicates a temperature input error, possibly due to limits or no input device.

E9: Pressure In

Indicates a pressure input error, often due to limits or no input device.

E10: Special Input

Indicates a special input error, often due to limits or connection issues.

E11: Not Used

This error code message is not currently in use.

E12: Low Pressure

Triggered when pressure measurement is below the low pressure switch setting.

E13: Over Range

Current measurement exceeds the meter's range, indicating an overflow.

E14: Totals Overflow

Totalizers cannot keep up with accumulated flow signals due to small units/pulse value.
