3540 mΩ HiTESTER
Component measuring instruments
Customize with BCD output, printer interface or RS-232C interface to suit your application needs.
Fast-response milliohmmeter offers
selectable manual measurement or
system integration.
The 3540 mΩ HiTESTER is a high performance low resistance tester
that includes a comparator function essential for component sorting, fast
16-times-per-second sampling, temperature compensation and auto-
ranging, and a choice of interfaces to meet your measurement needs.
The standard 3540 is the economical version without external control
interfaces, making it the no-fuss solution for manual testing.
For more advanced system integration capabilities, select Model 3540-
01 for a built-in BCD output interface providing for external control,
Model 3540-02 to output measurement results to a printer, and Model
3540-03 to add PC compatibility via a built-in RS-232C interface.

Internal Comparator with Fast 100-ms Response
Features
ꢀComparator function stores up to seven tables
ꢀDual comparator modes: Hi-Lo compares upper and lower
limits, and REF-% compares a range and standard value
ꢀFast response of about 100 ms (measuring pure resistance:
actual response depends on material under test)
ꢀTemperature compensation function measures temperature
and calculates value relative to copper at 20˚C/68˚F
ꢀ4-terminal method eliminates the effects of leads and contact
resistance
ꢀAuto-ranging function
ꢀDual power system: batteries or AC adapter
ꢀBCD, printer interface and RS-232C interface options in -01,
-02 and -03 suffix versions, respectively

ꢀ Comparator Function
The comparator includes a Hi-Lo mode for setting upper and
lower limits, and a REF-% mode for setting a standard value
and range.
Up to seven tables can be memorized, each storing a
measurement range, comparator mode and comparator values.
Hi/IN/Lo measurements are indicated by LED and
3-way beeper mode, and for the -01 and -02 versions, results
are available for external use at open-collector output terminals
on the rear panel.
Hi-Lo Comparator
REF-% Comparator
Example display with FAST sampling, measurement value 30.00 mΩ,
temperature compensation on, table no. 1, upper limit 30.10 and lower
limit 29.90, and beeper mode HL.
Example display with FAST sampling, 100.0% deviation of display from
standard value (displayed deviation = measured value / standard value ×
100%), temperature compensation function on, table no. 7, standard
value is 30.00, range is ±10.0%, and beeper mode IN.
ꢀ 3540
The basic version includes the essential functions: eliminating
external interfaces to keep the price low. Comparator results
are displayed by LED and beeper. Jacks are provided on the
rear panel for the temperature probe (for temperature
compensation), and for the AC adapter.

ꢀ 3540-01
This version is equipped with a digital interface providing
BCD output of comparator results and external control
capability, as well as the essential functions of the 3540. Along
with BCD output, the range, comparator tables, EOC and
power can be externally controlled, ideal for system
applications.
AUTO/MANU Select
Timing Chart Example
With AUTO selected, BCD and comparator results are output continuously. With
MANU selected, comparator results are output only when the MANU and GND
external input terminals are shorted together.
The following chart shows the timing relationships between
comparator results using the hold function and BCD output at
the external connector.

At Hold time, the EOC is retained until the next trigger to facilitate
sequencing. Display and output are retained until the next EOC is taken.
CC ERR input enhances test reliability with various materials under test
t1: (Settling time) after checking, the delay until measured power is stable
before triggering. Settling time depends on material under test (value
is relative to pure resistance).
Note: Signal Logic
TTL Outputs:assert = 5V, negate = 0V
TTL Inputs: assert = 0V, negate = 5V
Open Collector Outputs: assert = ON,
negate = OFF
t2: (Measuring) raising EOC accepts BCD and comparator results, so the
desired data is captured.
EOC and CC ERR are output from version -01 by both TTL and open
collector. Pin out details are available upon request.
