Group: Digital multimeter
Description: Megohmmeter/IR Tester
Information:
                                    The 1865 Megohmmeter/IR Tester is a general purpose high
voltage instrument for
resistance measurements on insulating materials and
components. It is designed for easy,
accurate and direct readings of high resistance typically
found in synthetic resins,
porcelains, insulating oils, plastics and other similar
materials. It is also used for
measurements on capacitors, transformers, switches, cables
and connectors. The 1865
provides a direct readout of resistance from 1000Ω to 1000TΩ
with fully automatic
ranging. The voltage applied to the unknown is programmable
from 1V to 1000V.
The 1865 includes a high resolution graphics display and
keypad for ease of use. The test
cycle is fully automatic with programmable charge, dwell,
measure and discharge times.
These times, along with other test conditions can be stored
in instrument memory and
recalled for later use. A pass/fail indicator provides the
operator with a visual indication
based on a preset resistance limit. The unit also contains
automatic zeroing at the test
leads as well as built-in self-test routines. Safety
features include current limiting to less
than 2mA and a front panel indication when voltage is
applied to the test terminals, thus
permitting connections to be made safely.
The 1865 comes standard with I/O Port (handler) and RS232
interface. An IEEE-488
interface is optional for communication with other
instrumentation and remote control
operation. A 3 1/2" floppy drive option is also available
for storing test conditions and
results. There is a direct reading current measurement mode
from 1mA to 1pA.
The unit is available with front or rear panel input
connections with guard and ground
terminals to permit measurements of grounded or ungrounded
devices.
