SECTION 1 GENERAL INFORMATION
1.1 INTRODUCTION
The MEMOCAL 2000 is a versatile, portable, hand-held calibrator
developed to solve two different and coexisting customer needs:
field calibration (maintenance) and laboratory calibration (mainte-
nance, quality test, process simulation, training, etc..).
- The field calibration requires small dimensions, no additional
accessories, long battery life, ergonomy, friendly interface, low
temperature drift, high noise immunity and simple programming
capabilities.
- The laboratory requires: interface for data loggers or supervision
and control systems, large range of I/O capabilities, high
accuracy and stability over time.
The features listed below give an idea of the possible applications
and use facility offered by this instrument
· Accuracy 0.015 % (*)
· Temperature drift 0.1 mV/°C
· Operates with standard 1.5 V AA type alkaline batteries or
rechargeable batteries (Ni-Cd or Ni-MH)
· Advanced battery power management for circuit stand-by mode
when not in use.
· 24 hours (average) battery life operation.
· Built in bi-directional RS-232 interface for remote programming
and data recording
· Autoranging during measurement and generation.
· Simulates and measures T/C signals (15 T/C type) and RTD
signals (Pt 100 and Ni 100).
· Generates and measures mA, mV, V and OHM signals.
