VICTOR 05S – The Complete Loop Calibrator and 0-30mA Signal Generator for Loop Professionals
1. All-in-One Loop Calibration – Source, Simulate, Measure, and Power
The VICTOR 05S is more than a calibrator – it’s a complete workstation. As a true Loop Calibrator and 0-30mA Signal Generator, it sources 0.000mA to 30.000mA with 0.05% accuracy, measures -30.000mA to 30.000mA at 0.02% accuracy, and also measures DCV from -30.000V to 30.000V. Add the built-in 24V loop power supply (10% accuracy), and you have one tool that replaces a separate source, multimeter, and loop power supply. Carry less, do more.
2. Outstanding 0.02% DCV Measurement Accuracy
Most Loop Calibrator units focus only on current. The VICTOR 05S gives you lab-grade voltage measurement too. With 0.02% + 2mV accuracy on the 30V range, this Loop Calibrator and 0-30mA Signal Generator can verify PLC analog outputs, chart recorder inputs, or isolate power supplies. 0.001V resolution means you catch millivolt-level drift before it becomes a process problem.
3. Precision Current Sourcing at 0.05% + 4µA
When you need a reliable 4-20mA test signal, the VICTOR 05S delivers. This Loop Calibrator and 0-30mA Signal Generator sources current with 0.001mA resolution and ±(0.05% + 4µA) accuracy. Use it to test valve positioners, I/P transducers, or variable frequency drive analog inputs. The stability means no more “is it my Loop Calibrator or the transmitter?” guesswork.
4. True 2-Wire Transmitter Simulation Mode
Switch to SIMULATE mode, and the VICTOR 05S acts exactly like a loop-powered transmitter. Your Loop Calibrator and 0-30mA Signal Generator draws power from the external loop and controls current precisely. Quickly test a DCS analog input card or a PLC channel without disconnecting field wiring. Troubleshooting takes minutes, not hours.
5. Large HD Backlit Display – Readable Anywhere
Dark panel rooms? Outdoor skids at dusk? No problem. The VICTOR 05S features an HD large screen with backlight. This Loop Calibrator and 0-30mA Signal Generator also includes a built-in flashlight for illuminating terminal blocks and wiring labels. Every detail is visible, reducing connection errors and eye strain.
6. Simple One-Handed Operation with Dedicated Controls
You have buttons for SOURCE ON, Set, 100%, 25%, MEASURE, RUN, START, CONFIG, ZERO, and FUNC. No buried menus. This Loop Calibrator and 0-30mA Signal Generator lets you toggle between sourcing and measuring instantly. Press FUNC to switch voltage/current modes. Press CONFIG to set ramp or step patterns. Your other hand stays free to hold test leads or a tablet.
7. 60V Peak Protection on Measurement Terminals
Worried about accidental overvoltage? The VICTOR 05S is rated MAX 60V PEAK on the MEASURE terminals and MAX 30V PEAK on SIMULATE. That means this Loop Calibrator and 0-30mA Signal Generator survives misconnections to 48V systems or charged capacitors. Built for industrial electricians who work fast under pressure.
8. Automatic Shut-Down and Low-Power Tips
Batteries die at the worst moments. The VICTOR 05S includes automatic shut-down to save power. Low-pressure (low battery) tips appear on screen before shutdown. This Loop Calibrator and 0-30mA Signal Generator keeps working through long shifts, and you get fair warning to swap batteries or finish a critical test.
9. Flashlight Lighting – See What You Connect
Unique among compact Loop Calibrator units, the VICTOR 05S has a built-in flashlight. When you are reaching into a dark junction box or behind a crowded panel, simply turn on the light. This Loop Calibrator and 0-30mA Signal Generator illuminates wire numbers, terminal screws, and fuse holders. No second person, no headlamp needed.
10. 24V Loop Power for Transmitter Testing
Need to power a 2-wire 4-20mA transmitter on the bench? The VICTOR 05S provides 24V loop power (10% accuracy). Connect the transmitter, power it from the Loop Calibrator, and measure its output simultaneously. This Loop Calibrator and 0-30mA Signal Generator becomes a complete transmitter test station – power, simulation, and measurement in one compact case.
11. Wide ±30mA Measurement and Sourcing Range
Many Loop Calibrator tools stop at 24mA or 25mA. The VICTOR 05S measures and sources up to ±30mA. That extra headroom lets you diagnose shorted loops, over-range transmitters, or non-standard sensors. As a Loop Calibrator and 0-30mA Signal Generator, it handles everything from 0-20mA to 4-20mA to 0-30mA industrial applications.
12. Easy 25% and 100% Quick Output Buttons
Testing linearity has never been faster. Press 25% to jump to 4mA, 8mA, 12mA, 16mA, 20mA in sequence. Press 100% to go directly to 20mA. This Loop Calibrator and 0-30mA Signal Generator also has a SET button for custom values. Perfect for three-point or five-point valve stroke checks.
13. Automatic Zero and Span with ZERO Button
One touch of ZERO outputs 4mA (or 0mA depending on mode). For quick zero checks of differential pressure transmitters or level sensors, this Loop Calibrator and 0-30mA Signal Generator saves menu navigation. Press START to begin auto-ramping. The VICTOR 05S makes repetitive testing efficient.
14. Rugged, Simple, Easy to Carry
Weighing almost nothing and fitting in a shirt pocket, the VICTOR 05S is designed for field use. The simple interface means new technicians learn it in under two minutes. This Loop Calibrator and 0-30mA Signal Generator is built with no sharp corners to snag on clothing or cable bundles. Take it from the maintenance shop to the top of a distillation column.
15. Trusted for HVAC, Water, Oil & Gas, and Pharma
Wherever 4-20mA loops control critical processes, the VICTOR 05S is the chosen Loop Calibrator and 0-30mA Signal Generator. Calibrate rooftop AHU actuators, test chemical dosing pumps, verify gas detector outputs, or simulate pH transmitter signals. The 0.05% basic accuracy meets ISO and FDA documentation requirements.
If you work with 4-20mA loops daily, the VICTOR 05S is the Loop Calibrator and 0-30mA Signal Generator you will reach for again and again. It sources, simulates, measures, and powers – all with a huge backlit display, flashlight, and one-handed controls. Stop carrying three tools. Start using the VICTOR 05S.
