This chapter describes how to set up and start the AT515 DC Resistance Meter.
Incoming Inspection
Power Requirements
Setting up the Fuse
How to Remove the Handle
Environmental Requirements
Cleaning
1.1 IncomingInspection
After you receive the instrument, carry out checks during unpacking according to the
following procedure.
WARN IN G
If the external face of the instrument (such as the cover, front/rear panel, LCD screen,
power switch, and port connectors) appears to have been damaged during transport, do
not turn on the power switch. Otherwise, you may get an electrical shock.
Make sure that the packing box or shock-absorbing material used to package the
instrument has not been damaged.
Referring to <Packing List> in the packing box, check that all packaged items supplied
with the meter have been provided as per the specified optioned.
NOTE
If an abnormality is detected, contact the company and transport the meter to your
nearest Applent Instruments sales or service office. For inspection by the transport
company, save the packing box, shock-absorbing material, and packaged items as you
received them.
1.2 SettingupFuse
~Line: 110VAC/220VAC, 50Hz/60Hz
Fuse: 250V 1A Slow Blow
Please use the following fuse type.
UL/CSA type, Slow-Blow, 5×20-mm miniature fuse, 1A, 250 V
When you need a fuse, contact your nearest Applent Instruments sales or service office.
To verify and replace the fuse, remove the power cable and pull out the fuse holder.
1.3 EnvironmentalRequirements
Set up the AT515 where the following environmental requirements are satisfied.
Operating Environments
Ensure that the operating environment meets the following requirements.
Temperature: 0C to 55C
Temperature range at calibration: 23C±5C (<1C deviation from the temperature
when performing calibration)

8 AT515 User's Guide
Humidity: 15% to 85% at wet bulb temperature ≤40 °C (non-condensation)
Altitude: 0 to 2,000m
Vibration: Max. 0.5 G, 5 Hz to 500 Hz
1.4 Cleaning
To prevent electrical shock, disconnect the AT515 power cable from the receptacle
before cleaning.
Use a dry cloth or a cloth slightly dipped in water to clean the casing.
Do not attempt to clean the AT515 internally.
WARNING: Don’t Use Organic Solvents (such as alcohol or gasoline) to clean the
Instrument.

This chapter contains general information about AT515 .The information is
organized as follows
Introduction
Main Specifications
Feature overview
2.1 Introduction
Thank you for purchasing AT515 Resistance Meter.
AT515 is an ultra-high-precision wide-range, high-performance ARM
microprocessor-controlled resistance meter. Its measurement range of 0.1Ω～1.2GΩ,
the maximum display number 1,200,000. The sampling-rate is 220times/s(4.5ms).
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.
With its built-in comparator, the AT515 can output comparison/decision results for
sorting components into a maximum of ten bins. Furthermore, by using the handler
interface, the AT515 can be easily combined with a component handler, and a system
controller to fully automate component testing, sorting, and quality-control data
processing.
AT515 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.

5.1.1 TRIGGER[DELAY]
In external trigger mode, to synchronize with external devices (such as PLC), you can
set the trigger delay time.
The trigger delay time is the interval time from receiving the trigger signal to begin
measure.
Procedure for inputting the trigger delay time:

5.1.3 TurnTemperatureCompensationON/OFF
SCPI Command: FUNCtion:TC {ON,OFF,1，0}
The AT515 built in Temperature Compensation Interface.
The Temperature Compensation Formula is:
Where,
T0: Reference Temperature
T: Current Room Temperature
α: Temperature coefficient of reference temperature (%)
F1: Without compensation value
F2: Temperature compensated value
Procedure for turning the temperature compensation ON/OFF
Step 1. Press the [Setup] key
Step 2. Use the cursor key to select [TEMP COMPENSATION] field
Step 3. Use the soft keys to turn on/off

5.1.4 Temperature[COEFFICIENT]α
SCPI Command: FUNCtion:TC:COEFficient <float>
Before using the Temperature Compensation Function, you must enter the coefficient of
the DUT material. Such as the coefficient of copper is 0.393%.
Procedure for inputting the coefficient:
Step 1. Press the [Setup] key
Step 2. Use the cursor key to select [COEFFICIENT] field
Step 3. Enter the coefficient value using the entry keys and press the Enter to confirm.
5.1.5 ReferenceTempera ture[REFERTEMP]
SCPI Command: FUNCtion:TC:REFEr <float>
The temperature unit is Celsius degree.
