Selectable Reference Currents from 100 nA – 1 A
For power sensitive applications such as fuses and resistors, multiple test current selections are
available.
Percent or Absolute Comparator with HI-GO-LO contact and TTL outputs
The 1750 microohmmeter design makes it easy to integrate into new or existing designs. There
are three comparator outputs which double as output bins 1, 2, and 3. The 1750 interface includes
relay and TTL outputs for comparator and bin functions.
Rear Panel TTL & Relay outputs for PLCs and interfacing
In addition to GPIB and RS232 interfaces, the 1750 provides a variety of TTL and relay contact
I/O’s designed to make integrating the 1750 into a test stand as versatile as possible.
1 year calibration cycle (after initial 6 month calibration)
After the initial 6 month calibration, the recommended calibration interval for the 1750 is every
twelve months.
10 Preset Storage Locations
Storage location 0 is reserved for recalling factory default settings. Locations 1-9 are user
definable and may be programmed manually or via communication interfaces. These settings are
stored in non-volatile RAM locations.
Fast Mode for high-speed measurement
Fast Modes allow speedy measurements of up to 100 reading per second. The time to first reading
is approximately 12 ms, faster than any other Ohmmeter in the market. This is obtained by using
a patent pending DSP technique developed by TEGAM.
½ Rack Width
Two 1750 microohmmeter units are able to be rack mounted, side-by-side, in a standard 19”
rack without modification to the 1750 case.
Manual or Auto Ranging
User defined ranging allows AUTO range or 19 user-selectable ranges of resistance and test
current. All ranges have a 15% over-ranging capability.
