  • immediate or delayed display of statistical values
  • immediate or delayed print-out of readings and statistics
  • display and print-out of date and time – year, month, day, hour and minute
GalvanoTest interfaces for peripheral devices
  • interface for MiniPrint data printer
  • interface for an RS 232 C for connection to a PC
  • analog output for connection to an x-t recorder to chart voltage curve
  • Electrolyte alarm/saturation indicator
Measuring uncertainty
5 % of reading on a measuring area of 8 mm2 after calibration
