"Weighing scale is not working! But I'm not sure which is actually broken, a load cell or an indicator…"
In such a case, failure judgments are possible with UNIPULSE products.
For checking indicators…
Precision Calibrator "513B"
Variable Checker "520A"
Both 513B and 520A are the calibrators capable of generating extensive pseudo output.
Output voltage can be adjusted with a dial on 513B and a trimmer on 520A.
By connecting to the sensor input of the indicator, you can confirm whether the display function of the indicator is normal. These calibrators can be also used for calibrations of indicators.
When inputting voltage, a correct value is displayed.
When inputting voltage, no response is shown or LOAD is displayed.
For checking load cells…
Portable Digital Indicator "F490A"
F490A is a compact, lightweight and handheld digital indicator for strain gauge type sensors.
Load can be checked at hand, and data is saved on the memory of the main unit. Perfect for daily press force checking.
Since a function to display output voltage of a load cell is also included, this instrument can be utilized for failure judgments of load cells too.
When pressing with a press machine etc., output value is displayed.
Even if pressing with a press machine etc., output voltage does not fluctuate.
When connecting, "LOAD" is displayed.
