RONAN X86 calibrator with Carrying case, Charger and Manual.

Description

RONAN X86 calibrator
with Carrying case and Charger
1.0 GENERAL DESCRIPTION
The Ronan Model X86 Portable Calibrator is a versatile
instrument, developed to calibrate and measure instruments
and systems, utilizing current, voltage or ohms inputs and
outputs. In addition to mA, mV and volt ranges, the Model X86
has a resistance capability that provides for calibration and
measuring of resistance temperature detecting (RTD) devices.
The Model X86 features separate input and output sections,
each with full, independent controls and displays. The two,
4 1/2-digit liquid crystal displays provide measurement and output
resolutions of 0.01% of range (0.017% resolution for 60 mA
output range). The input and output sections are isolated, so the
Model X86 will not introduce ground loop problems, when it is
fully utilized in instrumentation loops and systems.
The Model X86 features easy range and value selection through
the use of individual pushbutton switches. Up to four output
values can be stored and recalled from internal memory at the
touch of a button. The calibrator can also be set to
automatically sequence through the stored values at a
selectable speed.
The Model X86 has a pair of two-wire terminals that provide
simulation of a two-wire transmitter in a voltage-powered
current loop.

Out-of-Range Indication
The flashing 1digit on the displays indicates a probable output
error for the following conditions
:
a) The calibrator is set to the mA output range and the output
loop is open.
b) The calibrator is set to the mA output range and the loop
voltage drop is too high
