MNM Comp-1K-0.1 1,000 lb x 0.1 lb LP7515 Compression Scale Guide
The MNM Comp-1K-0.1 is a calibrated 1,000 lb x 0.1 lb tension/compression force system built around an alloy-steel S-type load cell and an LP7515 LCD indicator. It is a useful range for springs, actuators, clamps, light presses, assembly fixtures, pull/push testing and bench force stands where a 1,000 lb maximum is enough and tenths-of-a-pound display increments are helpful.

What the LP7515 adds
LOCOSC publishes LP7515 functions including zero, tare, accumulation, animal weighing, Peak/Data Hold, check weighing and kg/lb switching, with optional RS-232 on some versions. The LP7515 family is designed to read strain-gauge load cells and provides configurable decimal, division, maximum-capacity and calibration-load parameters. Connector and enclosure versions vary, so match the exact hardware supplied by MNM before replacing an indicator.
Setup and mounting
Use the S-type load cell in a straight axial load path. For compression testing, a guided test stand or fixture should keep the applied force centered and prevent the load cell from tilting. For tension, use rated rod ends or eye bolts that remain aligned as force increases. Avoid side load, bending, cable pull and sudden impact. Zero the system with all normal adapters or preload hardware installed in the same condition used for testing.
Calibration and verification
The LP7515 has a documented calibration flow. Configure decimal point, division, maximum capacity and calibration loading weight; enter `[CALon]`, perform unloaded zero at `[noLoAd]`, apply the defined known load at `[AdLoAd]`, press HOLD after the reading is stable, then save at `[CALEnd]`. Public LP7515 documentation states a calibration load should be at least about 10% of maximum capacity, with roughly 60-80% preferred when practical and safe.
Manuals & Technical Documents
Best applications for the 1,000 lb range
The Comp-1K-0.1 fits work where the maximum expected force is comfortably below 1,000 lb: industrial and automotive springs, actuator push force, small hydraulic or pneumatic cylinders, clamp-force verification, cable pull tests, valve components, assembly force, light press fixtures, fastener pull setups and comparative quality-control tests.
Troubleshooting
Unstable display: check fixture movement, side load, battery state, connector/cable condition and electrical noise.
Does not return to zero: inspect preload, binding, overloaded adapters and load-cell damage.
Peak reading varies excessively: standardize loading rate, fixture alignment and starting position before blaming calibration.
Calibration error: verify configured capacity, division and known calibration load, then repeat zero/span with a stable reference.
FAQ
Can the Comp-1K-0.1 measure both tension and compression?
The S-type sensor format supports tension/compression measurement when the fixture is designed for each direction. The MNM listing is marketed as a compression scale, so confirm your tension hardware and safe load path before use.
Is 0.1 lb readability the same as 0.1 lb accuracy?
The listing describes 0.1 lb accuracy/readability, but real measurement uncertainty also depends on calibration, mechanics, temperature, repeatability and the reference standard. Treat the displayed increment as one part of system performance.
When should I choose 2,000 lb instead?
Choose more capacity when expected peaks, preload, shock or safety margin make 1,000 lb too close to the maximum. The comparison page explains the 1,000 x 0.1 and 2,000 x 0.2 choices.
