The MNM Scales 1,000 lb x 0.1 lb S-type tension/compression scale combines a 1,000 lb alloy-steel S-beam with a rechargeable digital indicator, two eye bolts and a calibrated ready-to-use setup. The 0.1 lb display increment makes this capacity especially useful for spring, cable, actuator, hanging-load and general industrial force work where a 500 lb system may not provide enough range but a multi-thousand-pound system would sacrifice useful sensitivity or cost more than necessary.
Published MNM Specifications
MNM lists the system at 1,000 lb capacity with 0.1 lb displayed accuracy/increments and Peak Hold. The package includes an alloy-steel S-type load cell, digital indicator with rechargeable battery and power supply, and two eye bolts. Published indicator functions include zero, gross/net/tare, accumulation, printing, counting, check weighing and auto-hold, with selectable lb/kg units, RS-232 output and a 6-digit 1-inch LED/LCD-style display. The listing also states that the indicator can drive multiple 350-ohm load cells, although the exact indicator model is not named on this product page.
Why the Unspecified Indicator Model Matters
The product page describes the indicator’s capabilities but does not identify a model number. That distinction matters for calibration menus, connector pinouts and serial settings. Before following a model-specific service manual, confirm the model printed on the actual indicator supplied with the system. The general weighing and force-measurement principles remain the same, but button sequences and parameter numbers can differ.
How the S-Beam Works
S-type load cells use a strain-gauge bridge bonded to a machined elastic body. Axial tension or compression creates a small deformation and corresponding electrical signal. The indicator converts that signal into a calibrated reading. Keep the sensor centered in the force path; side load, twisting or bending can reduce measurement quality and can stress the cell or fittings.
Where a 1,000 lb x 0.1 lb System Fits
For springs, cables, linear actuators and component testing, read the 1,000 lb spring, cable and actuator guide. For suspended-force and rigging applications, see the hoist, hanging-load and rigging force guide.
Setup Tips
Install the load cell with rated hardware and a straight axial load path. Power on with no applied test force, confirm stable zero, then load smoothly. If the test objective is comparison, maintain the same fixture geometry and loading rate. Use Peak Hold when maximum force matters more than a live reading. After unloading, verify the display returns near zero. A changed zero is often a useful early warning of fixture movement, overload, wiring problems or calibration drift.
Calibration and Verification
MNM sells the system calibrated and ready to use, but verification remains important after shipping, fixture changes or heavy use. The dedicated calibration guide explains how to check zero, apply known reference loads, evaluate repeatability and decide when model-specific service calibration is appropriate.
Manuals & Technical Documents
The exact indicator model is not identified on the current MNM listing. Confirm the model printed on the supplied indicator before using a model-specific user or calibration manual. MNM can help identify the correct document at (832) 290-3120 or mnmscales@yahoo.com.
Frequently Asked Questions
Can this measure both tension and compression? The S-type sensor geometry supports both when the fixture is designed correctly. Does it have Peak Hold? Yes, Peak Hold is listed by MNM. Is the system calibrated? MNM lists it as calibrated and ready to use. Does it support data output? The listing specifies RS-232. Is 0.1 lb the total accuracy? Treat 0.1 lb as the displayed increment from the listing; total measurement uncertainty also depends on calibration, load-cell behavior and setup.
