1. Introduction
The VICTOR 15+ is a handheld, battery-operated multi-function calibrator designed for precise measurement and sourcing of various electrical and physical parameters. It is an essential tool for calibrating 2-wire pressure transmitters, pressure switches, and for working with voltage, current, resistance, frequency, pulse, thermocouples (TC), and Resistance Temperature Detectors (RTD).
Key features include:
- High basic accuracy of 0.02%.
- Large digital LCD for clear display of measurements.
- Simultaneous display of TC/RTD measurements with mV/Ω and mA with mA%.
- Functions for sourcing DC voltage, DC current, resistance, frequency, and pulse.
- Ability to simulate transmitters, thermocouples, and RTDs.
- Automatic shut-down feature to conserve battery life.
- Data retention (HOLD) function.
- USB communication for data transfer.
- Backlight function for visibility in low-light conditions.

5. Maintenance
5.1 Cleaning
To clean the calibrator, wipe the exterior with a clean, damp cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off and disconnected from any circuits before cleaning.
5.2 Fuse Replacement
If the calibrator fails to power on or experiences issues with current measurement/sourcing, the internal fuse may need replacement. Refer to Figure 3 for the fuse location within the battery compartment. Use only fuses of the specified type and rating.
5.3 Battery Care
Remove batteries if the calibrator will not be used for an extended period to prevent leakage. Replace all four AAA batteries simultaneously with new ones when the low battery indicator appears on the display.
