Calibration is the determination and documentation of deviations in a measuring device. This measuring device is compared with the measurement result of another measuring device (or standard), whereby the standard is traceable to national or international standards and therefore its correct and accurate function is known.
Adjustment
Adjustment involves intervening in the device to minimize a detected measurement deviation. Normally, a further calibration is carried out after an adjustment to verify that the intervention in the device was correct.
Traceability
Traceability involves comparing the measured value of a measuring device with a national or international standard. At each step, according to the hierarchy of standards, a measuring device is compared with a standard, which in turn has been calibrated with a higher-level standard. The calibration hierarchy ranges from company test equipment, working or factory standards, to reference standards and national standards.
Measurement uncertainty
Measurement uncertainty is a non-negative parameter and is specified without a sign. It characterizes the dispersion of the values associated with the measured quantity based on the information used.

Description
LR-Cal TLDMM-3.0 description
The LR-Cal TLDMM-3.0 is a professional digital pressure pressure meter manufactured with the most modern technologies to ensure a high degree of reliability, versatility and practicality. A monolithic sensor made of stainless steel, which can also withstand very dynamic pressures and a robust housing made of painted, reinforced technopolymer guarantee great robustness and high long-term stability.
The device was developed for use in metrological laboratories,calibration systems, in automation technology in general and in process control, where it is also necessary, for example, to monitor, record andmonitor, record and transmit data.
During the production cycle, the LR-Cal TLDMM-3.0 is calibrated and supplied with a DAkkS-approved ACCREDIA certificate to guarantee a measurement uncertainty of better than 0.025% or 0.05% in 30 different pressure ranges, gauge pressure, including manovacuum ranges, and absolute pressure.
With the LR-Cal TLDMM-3.0 it is possible to simultaneously measure the pressure generated by air, gas, oil, water or any other type of non-corrosive liquid and the temperature of the pressurized medium.
The LR-Cal TLDMM-3.0 is powered by an internal, rechargeable lithium-ion battery with up to 50 hours of continuous operation (without backlight). To charge the battery, you can use the USB port with the 5 VDC power supply or connect the device directly to the USB port of a PC.
For continuous operation, the pressure gauge can be supplied with power via the USB port. For industrial applications, it is optionally possible to use an external power supply from 12 to 24 VDC (device then without built-in battery).
In the programming menu, which is accessible via the keypad, the behavior of the device can be adapted by setting various functions, such as DIGITAL FILTER, which makes it possible to keep the measured value display stable even with discontinuous pressures, resolution, unit of measurement, automatic switch-off, etc. ...
A positive and negative PEAK function (peak value) can be set via the keypad in order to record the maximum and minimum pressures determined during a test. There is a bar graph on the display, which is also always active in the programming menu.
For easier installation and better readability, the display can be aligned by up to 90°. The optional WIRELESS function is used for wireless transmission of measured values in a network of up to 32 devices. A communication protocol for the user's own PC software is available on request.

LR-Cal LPP 140-P: Pneumatic pressure test pump up to 140 bar / 2,030 psi
It has never been so easy to generate pneumatic test pressures of up to 140 bar / 2,030 psi.
The new LR-Cal LPP 140-P impresses with its performance and ease of use. The lever pump not only generates pressures up to 140 bar / 2,030 psi (with ambient air) but can also be switched to vacuum generation (down to -0.95 bar / -14 psi).
Both the reference pressure gauge and the test specimen can be mounted in the pressure connections (quick-action clamping devices) without tools. Various internal threads are available, the basic equipment includes 2 connections with 1/2" BSP female threads. Two blanking plugs for shut-off are also included in the scope of delivery.
The test pressure can be set particularly sensitively via a fine adjustment valve with a resolution of better than 1 mbar.
