The HP-YBMN4 is a precision strain gauge simulator / Wheatstone bridge calibration box designed to verify and calibrate strain meters, strain amplifiers, and data acquisition strain channels. It uses an internal calibrated standard bridge and manual range switching to output controlled differential voltage (or equivalent microstrain) for reliable static calibration.

HP-YBMN4 is built around an internal calibrated Wheatstone bridge (standard resistor network). By selecting ranges and adjusting front-panel knobs, users can generate repeatable simulated strain outputs (microstrain equivalents) to:
verify the strain system’s linearity and indication accuracy,
perform static calibration of high-precision strain instruments,
check bridge wiring correctness and system stability in lab or field setups.
Static calibration of strain indicators / strain meters
Calibration and verification of strain amplifiers and strain DAQ channels
QA checks for Wheatstone bridge measurement systems
Lab setup validation for structural testing, mechanical testing, and research instrumentation
Troubleshooting wiring and bridge configuration errors before running experiments
Compatible Inputs/Systems
Strain meters / strain indicators
Strain amplifiers / signal conditioners
Strain-capable DAQ systems (bridge input modules)

1) What is a strain gauge simulator used for?
It generates a stable, calibrated “simulated strain” output (differential bridge signal) to verify and calibrate strain meters, strain amplifiers, and DAQ strain inputs—especially for static calibration.
2) Can HP-YBMN4 work with quarter/half/full bridge setups?
Yes. It supports full bridge, half bridge, and quarter bridge output modes.
3) What bridge resistance does it simulate?
It uses a standard 120 Ω bridge network.
4) What excitation voltage can I use?
The bridge excitation range is 1–10 VDC.
5) How stable is the output over time?
Drift is specified at 0.5 με / 4 hours, which is suitable for long calibration sessions.
6) Do I need warm-up time before calibration?
Yes—allow about 20 minutes of warm-up for best stability and repeatability.
