2.1 Introduction
Thank you for purchasing AT510x DC Resistance Meter.
AT510x is a high-precision wide-range, high-performance microprocessor-controlled
resistance meter. Its measurement range of 1～
Ω20MΩ, the maximum display number
30000. Test speed of 15 times / sec, it still can guarantee high test accuracy, and reading
can be controlled beating 3 words or less. It is unique to the current modes of three tests to
adapt different requirements. Sorting equipment with professional features, with a group
of stored data, various sorting information ring settings, can also be equipped with
Handler interface, used in automatic sorting system to complete fully automatic
production line testing. And an optional RS232C interface or IEEE-488 interface for
remote control, data acquisition and analysis.
Computer remote control commands compatible with SCPI (Standard Command for
Programmable Instrument Programmable Instruments standard command set), complete
and efficient remote control and data acquisition functions.
AT510x measures of high, medium and low-value resistor; various switch contact
resistance; connector contact resistance; relay line package and the contact resistance;
transformers, inductors, motors, deflection coil winding resistance; wire resistance; cars,
boats, aircraft riveting metal resistance; printed version of the line and pore of resistance
and so on.

AT510X’s comparatorcan be turned OFF by pressing Comp key.
When the comparator function is OFF, sorting system will no longer work and the
Handler interface signals on the comparator output will be shut down.
4.1.1 SetupComparatorRecordFileNumber（invalidatAT510L/AT510Mversion）
1．Press Shift Comparator to the setup comparator.
2．Rec.09 indicator at the lower right corner of screen
flashes means you can setup record number.
3．Press < >or twist knob to choose the record
number which built-in 30 files.
4．Press digits to input value.
a. Press Enter to input nominal value and limit
value.
b. Press Esc to exit setup comparator and the
record file is saved.
4.1.2 Setupnominalvalueandlimitvalue
1．Press Comparator key to the setup comparator
status.
2．Repeat steps from 2-3 and press Enter to input the
comparator status and the digits are blink.
3．Press < > keys or twist knob to choose the
resistance’s nominal value (1st line), upper limit
value (2nd line) and lower limit (3rd line)
4．Press digit number keys or Enter key to input the
value.
5．Press Enter key orShift + Unit keys to input the
current value.
6．Repeat steps from 3~5 to input the other values.
7．PressEsckey to exit the setup and return the
measurement status.
TIP：
Using skill：The present value is flashed ,you can press digits to input the value
directly and it’s not necessary to press the Enter key first to enter the input status.
NOTE：In the number input status, press Enter key, the unit is 1.
For example：10+Enter :input value is :10。
In the range hold status (“AUTO” indication is OFF), Meter will select the range by
the upper limit value when it is exit setup status.

4.1.3 TurnON/OFFBeep
Press Beep key to turn ON/OFF beep function.
Indication is ON, the beep function is ON.
4.1.4 SetupBeep
1. Press Shift + Beep keys to the beep setup status.
2. Twist the Knob to choose: GD(Pass), NG(Fail).
3. Press Esc key to exit the setup and back to the measurement state.
4. Press Enter key to end the setup and back to the measurement status.
4.1.5 Flowofcomparatorwork
When the comparator function is enabled, the measure value compares with the upper
limit and the lower limit values.

5. HandlerInterface
Note：AT510PRO/AT510 (Standard interface), AT510SE/510L/510M(Optional
interface).
This chapter provides information of AT510x’s built-in handler interface. Include:
Pin Assignment
Circuit Diagram
Timing Chart
The AT510x’s built-in handler interface outputs signals that indicate the end of a
measurement cycle, the result of bin sorting by the comparator. In addition, the instrument
accepts input of external trigger. You can use these signals to easily integrate the AT510x
with system controller.
