Overview

The DEPRAG ME5000 is an electronic torquemeter designed for the precise monitoring of various transducers in industrial environments. This operating instruction booklet, identified as 012805en and document number 385484 A, provides comprehensive guidance for its safe and effective use.

Function Description:

The primary function of the ME5000 is to monitor Piezo-Transducers, Strain Gauge Transducers, or external Rotary Type Transducers. It is capable of measuring and displaying torque values, calculating statistical data such as average torque, standard deviation, and Cmk-value for measuring series. The device is designed for short-term machine capability tests, focusing on recognizing machine influences on the production process. It enforces a zero-point adjustment with each measurement, determining positive and negative zero-point deviations over 100 values, which are then deducted from the corresponding peak-value. The torquemeter can measure signals up to 10 kHz.

The ME5000 integrates a charge amplifier that transforms the emitted electrical load from the transducer into an electronic voltage. Due to the inherent drift characteristic of charge amplifiers, it is crucial to initiate measurements immediately prior to screw driving to ensure accuracy. The device supports both automatic signal recognition and START/STOP signal recognition for peak-value measurements. In automatic mode, measurement continues until the input signal drops to 40% below the maximum measured value after a threshold signal is recognized. In START/STOP mode, the user manually stops the measurement.

Important Technical Specifications:

  • Model: ME5000
  • Order No.: 385484 A
  • Dimensions (Measuring Instrument): 106 x 224 x 40 mm (L x H x W)
  • Dimensions (Charger): 100 x 155 x 50 mm (L x H x W)
  • Weight (Measuring Instrument with Battery-Pack): 0.54 kg / 1.19 lbs
  • Weight (Charger): 0.48 kg / 1.06 lbs
  • Voltage: 6 V (AKKU) – 7.5 V (Batteries)
  • Power Consumption: Approx. 400 mA
  • Measuring Ranges: 6 ranges, from approx. 1 Ncm to approx. 400 Nm (depending on the transducer used).
  • Signal Measurement Frequency: Up to 10 kHz.
  • Storage: Flash-ROM for retaining all parameters when the unit is off or in standby.
  • Battery: Built-in battery-pack (AKKU) with a dedicated charger (ACS 110 traveller).
  • Connectivity: RS232 serial port for PC or printer connection.

Usage Features:

The ME5000 features a user-friendly keypad with SET, UP, DOWN, START, and STOP keys.

  • Standby Mode: The instrument enters standby after 5 minutes of inactivity, displaying "STANDBY". Any key press activates it.
  • Menu Operation: Pressing SET accesses the main menu, which includes:
    • MEASURING TRANSDUCER: Selects the transducer type (Piezo, Strain Gauge, Rotary Style) and allows input of appropriate calibration values.
    • MEASURING RANGE: Selects one of six dynamically matched measuring ranges. The expected measuring value should ideally fall within the upper third of the selected range.
    • CALIBRATION VALUE: Allows input of a new calibration value.
    • MEASURING SERIES: Configures the number of measurements per series (up to 100 values) and allows selection of stored series for printing. Up to 40 measuring series can be stored.
    • SIGNAL RECOGNITION: Toggles between automatic and START/STOP signal recognition methods.
    • MEASURING METHOD: Selects between individual measurements and measuring series.
    • MEASURING UNIT: Selects the desired unit (N-cm, N-m, kg-cm, k-gm, oz-in, lb-in, lb-t).
    • LANGUAGE: Selects between German and English.
  • Peak Value Measurement: The highest measured positive or negative value is displayed.
  • Measuring Series: After each series, the average torque, standard deviation, and Cmk-value are calculated. Measuring values can be stored with an 8-digit identifier. A started series can be stopped using the UP or DOWN arrow keys.
  • Reset Function: A Reset-key allows restarting the instrument if it becomes unresponsive.

Maintenance Features:

  • Calibration: For quality assurance and audit documentation, factory calibration every 12 months is recommended. DEPRAG offers calibration services for instruments, transducers, and complete measuring chains.
  • Battery Charging: The ME5000 uses a built-in battery-pack charged via a docking station and the ACS 110 traveller charger.
    • Charging Indicators: Red LED "Power" (charger operational), Red LED "Charge" (battery-pack inserted), Green LED "Ready" (battery-pack charged, blinks during constant charge maintenance).
    • Initial Charge: The first charge may take up to 2 hours. If the green LED blinks after 15 minutes, the unit should be removed and re-inserted into the charging point.
    • Unload Button: A yellow unload-button, when pressed for approx. 2 seconds, releases the battery-pack.
    • Safety: Only the supplied charger unit should be used for the built-in battery-pack/rechargeable batteries. Standard batteries should never be used. Incorrect battery insertion (polarity) poses explosion and fire hazards. The instrument automatically shuts off when the battery-pack loses charge to prevent incorrect measurements.
  • Software Updates: Software updates and PC-Software with connection cables are available upon request.
  • Troubleshooting: A dedicated section provides guidance for common issues such as no display, instrument not reacting to start signal, or incorrect/varying measuring results, along with potential causes and solutions (e.g., charging battery, checking cable connections, verifying calibration values). If issues persist, the instrument should be sent to DEPRAG for evaluation.
  • Disposal: The instrument must be completely disassembled and all materials sorted and disposed of according to local environmental regulations.

The DEPRAG ME5000 is a robust and versatile electronic torquemeter, designed to provide accurate and reliable torque measurement and analysis in various industrial applications, from simple hand-tool monitoring to complex screwdriving robot systems.
