Description

LR-Cal LHM description

The particularly versatile and high-precision handheld LR-Cal LHM is not only suitable for highly accurate measurements of pressures, forces, weights and torques on site, but above all for calibration and adjustment tasks - mobile and in the laboratory.

The analog/digital converter processes 50,000 digits, the internal sensors and the available external sensors (2mv/V) can be calibrated and linearized menu-driven.

Free software LR-Cal LDM-COM

Under “LR-Cal LHM: DOWNLOAD” at the top of this page you can download the free LR-Cal LDM-COM software (for Microsoft®Windows®). It offers you three operating modes:

Calibration (calibration table):
Recording of the data measured during calibration of devices and storage in a data table.
Data recording
Automatic recording (logging) of measured values (with date and time stamp) at an adjustable time interval.
Read out memory:
Downloading data from the calibrator's memory.
