Software

DSC 24 Channel Logging : Version 1.2.0 View and log data from up to 24 DSC, DLC or DSCUSB modules.
Instrument Explorer : Version 2 build 2.0a This software allows the user to quickly set up and start to use the digitisers and indicators that Mantracourt offers. Capabilities include event monitoring and data logging, as well as calibration and configuration.

Q: You offer two versions – industrial stability and high stability - of the DSC and DCell, what is the difference?: A: The Industrial Version offers 25ppm basic accuracy (equates to 16 bit resolution). The High Stability version offers 5ppm basic accuracy (equates to 18 bit resolution) with comparable stability which far exceeds standard instrument performance.
Q: Are the DSC devices low-power?: A: Yes, low-voltage DC supply (5.6V min), typically 40mA for RS485 &.52mA for RS232 (including 350R strain gauge).
Q: Is there adjustable sensitivity?: A: Yes, the DSC devices can be configured for standard 2.5mV/V full-scale strain gauges as supplied. A single additional resistor configures the input between 0.5 and 100 mV/V full-scale.
Q: Do you offer linearity compensation?: A: Yes, advanced 7-point linearity compensation.
Q: Are there self-diagnostics?: A: Yes, the DSC devices offer continuous monitoring for faults such as strain overload, over/under-temperature, broken sensors or unexpected power failure. All fault warnings are retained on power-fail.
