Main Features and Advantages
Dual-Channel Efficiency: The MICROSET 104988-E03 uniquely operates both channels independently – simulating a thermocouple on Channel 1 while measuring 4-20mA output on Channel 2 – eliminating need for multiple tools.
Metrology-Grade Precision: Featuring 24-bit ADC resolution and auto-zero compensation, it achieves ±0.02°C stability for RTD calibrations, critical for pharmaceutical validation.
Smart Automation: Pre-programmed IEC 60751 (RTD) and ASTM E230 (T/C) curves with customizable test sequences (ramp/soak/step) reduce human error. The 104988-E03 automatically logs data with timestamps for audit trails.
Enhanced Field Usability: IP54-rated magnesium alloy case withstands drops up to 1m. The sunlight-readable display shows live sensor error (%) and battery health. Proprietary low-drift circuitry maintains accuracy despite temperature fluctuations.
Seamless Integration: Export calibration certificates via USB/Bluetooth to LIMS/CMMS. TMT-Control software enables remote operation and batch reporting. The 104988-E03 includes built-in HART communicator functionality for transmitter configuration.
Application Field
The MICROSET 104988-E03 excels in precision temperature calibration across regulated industries. In pharmaceutical manufacturing, it validates bioreactor probes (RTDs) per FDA 21 CFR Part 11 requirements. Oil refineries deploy it for furnace thermocouple surveys and safety shutdown system (SIS) verification. Power plants use the 104988-E03 to calibrate turbine exhaust thermocouples and reactor coolant sensors. HVAC technicians leverage its dual-channel mode to balance building automation sensors while simulating setpoints. Food processing facilities rely on its IP54 rating for sanitization-area transmitter calibrations. The instrument’s NIST traceability satisfies ISO 9001/17025 compliance for calibration labs servicing pressure transmitters with integrated temperature compensation.

Installation and Maintenance
Pre-installation preparation: Fully charge the 104988-E03 before field use. Install TMT-Control software for certificate templates. Verify probe compatibility (select correct sensor type in settings). For hazardous areas, ensure intrinsic safety certifications match zone requirements.
Maintenance recommendations: Perform annual factory recalibration (recommended cycle). Clean terminals with isopropyl alcohol monthly. Store at -10°C to 40°C in protective case. Update firmware via USB-C when notifications appear. Replace battery if runtime drops below 4 hours.
