Calibration constants are used by the gauges to perform the calculations
necessary to process raw count data into a density. Density and moisture tables
may be used for any gauge, but are more common with units that do not have
internal memory or an internal processor. Gauge manufacturers use NVRAM
(Non-Volatile Random Access Memory) or EPROM’s (Erasable Programmable
Read-only Memory) in their gauges.
Calibration constants may be entered into a gauge (CPN MC3, MC3 Elite, MC1
Elite, Humboldt EZ and SD, InstroTek 3500 and Troxler 3430, 3440, 3430 Plus and
3440 Plus) using the operating keypad. Units that employ EPROM’s (Troxler 3411
and Humboldt 5001 series) may operate using density tables while an EPROM is
programmed and mailed for installation. InstroTek can program EPROM’s for
your gauges. Simply fax or mail the Calibration Constants Report and InstroTek
will program and ship your EPROM by Priority Mail for a nominal charge. You
can also purchase a Prom Programmer Package to burn proms at your facility.
VeriFier allows creation of hexfiles for Troxler 3411B and Humboldt 5001C gauges.
There is an option available on 3401 and 3411 gauges that you can use to allow
direct entry of constants through the keypad. SmartPanel from InstroTek is a
“drop in” replacement for the existing 3401 and 3411 scalars. SmartPanel
upgrades the 3401 and 3411 gauges with many features, including direct entry
of calibration constants through the keypad. For more information on the
InstroTek SmartPanel, please visit our website at www.InstroTek.com.
