Features of the CALOG Calibrators – Loadcell II Calibrator
* Portable Loadcell fault finder
* No need to disconnect loadcell — you can do it in situ (onsite)
* Insulation of the loadcell to check for water ingress. Normally measured at 50VDC this is the minimum resistance between the metal body of the load cell and any of its electrical connections.
* Simulate Load output to controller
* Local designed product – Made in South Africa
* SD card for storing / data logging results
* Ruggered
* Loadcell display – LCII will excite the laodcell and measure the output
The CALOG Calibrators – Loadcell II Calibrator is ideal for testing 4 and 6 wire loadcells, checking insulation breakdown, weighing system calibration and simulation.
It can test a loadcells’ zero balance, input resistance, output resistance, bridge balance, 50V DC insulation test from bridge to shield, bridge to housing and shield to housing.
The CALOG Calibrators – Loadcell II Calibrator is a hand-held precision calibrator specifically designed for load cell testing, including insulation breakdown and weighing system calibration or simulation. Simply connect a strain-guage load cell to the spring terminals and press “TEST LOADCELL”. The backlit graphics will display four or six wire, zero balance, input or output resistance and bridge balance. It can then carry out a 50 VDC insulation test form bridge to shield, bridge to housing and shield to housing.
For system testing and calibration the CALOG Calibrators – Loadcell II Calibrator can simultaneously measure mV (with mass display), excitation voltage and mA. In source mode, used for load cell amplifier pre-calibration testing, it can source mV (with mass display), measure excitation and measure mA. In simulate mode it sources a mA signal to the control room or SCADA. The display can be in mA, mA and mass or mass and mA.
* Measure, source and simulate 0 to 24 mA with 1uA resolution
* Measure 0 to 20 V with 1mV resolution
* Measure -4.5 to 35 mV with 1uV resolution
* Measure mV, mV & Mass or Mass & mV
* Source mV, mV & Mass or Mass & mV
* Simulate mA, mA & Mass or Mass & mA
* Built-in 24V power supply for mA loops
* 1 year guarantee (batteries not included)
* Carry case, protective rubber boot, charger and test leads supplied as standard
