Chapter 1 General Information

Thank you for purchasing and using our products. Before using the instrument, first inspect it according to the

“1.5 Unpacking Inspection” section of this chapter in this manual. If there is any discrepancy, please contact our

company as soon as possible to protect your rights. If you still have questions after reading this manual, please

contact your local distributor or call our company's engineers directly for further consultation.

1.1 Feature Overview

The ST1963 is a 6½ digital multimeter with high accuracy, stability and speed. The digital multimeter provides a

maximum measurement speed of 1000 readings/sec. ST1963 has a 0.0035% DC voltage basic accuracy, 0.0100%

basic resistance accuracy and other high performance.

ST1963 has broad measurement ranges:

DC voltage from 0.1μV to 1000V

AC voltage from 0.1μV to 750V, peak value of 1000V

AC/DC voltage from 1μV to 750V (RMS)

DC current from 10nA to 10A

AC current from 10nA to 10A

Resistance measurement from 0.01mΩ to 120MΩ

Frequency from 2Hz to 1MHz

Some additional capabilities of Model ST1963:

Full range of functions: In addition to those listed above, ST1963 functions include period, dB, dBm,

continuity, diode testing, arithmetical operation (mX+b) and percent.

Programming languages and remote control interfaces: ST1963 provides the SCPI programming

language and the remote control interface ports USB Device, RS-232C, LAN, IEEE-488/GPIB (option),

and Handler (option) interface.

Readings and instrument settings: Up to 10,000 readings can be stored in local mode.

Completed calibration: The unit can be calibrated either from the front panel or through the remote

control interface.

1.2 Operating Environment

Power supply: 110V/220V ±10%

Line frequency: 50Hz / 60Hz ±5%

Power consumption: ≤30VA

Operating temperature: 0°C to 40°C

Humidity: ≤ 90%RH

1.3 Dimensions and Weight

Dimensions (W×H×D): 225mm×100mm×355mm

Net weight: Around 2.5Kg

1.4 Safety Symbols and Precautions

The symbol on the instrument indicates that user should refer to the operating instructions located in the

manual before performing.

The symbol on the instrument shows that high voltage may be present on the terminal(s). Be careful to

avoid personal contact with these voltages.

The symbol on the instruments means earth grounding.

The WARNING heading used in the manual explains high voltage danger that might result in personal injury or

death. Always read the associated information very carefully before performing the indicated procedure.

The CAUTION heading in the manual reminds user that hazards could damage the instruments if not according

to operating instructions. Such damage may invalidate the warranty.

1.5 Unpacking Inspection

Your ST1963 was carefully inspected mechanically and electrically before shipment. After unpacking all items

from the shipping carton, please check for any obvious signs of physical damage that may have occurred during

transportation. Report any damage to the shipping agent immediately. Save the original packing carton for

possible future reshipment. The following items are included with every Model ST1963 order:

Model ST1963 61/2Digital Multimeter

Test leads (Model ST26036)

USB interface connection cable (ST26017)

Power cord

T500mAL fuse

T3.15AL fuse

Test report

This operation manual

Other optional accessories, if ordered

Verify that you have received all the items above when you get the multimeter. If anything is missing, please

contact our representative or our sales office.

Note: The IEEE-488 interface and Handler interface of this instrument are optional and need to be purchased

separately. These two interfaces cannot be installed at the same time.

1.6 Mark

The following marks are on each instrument panel or nameplate:

•Manufacturer's name or trademark

•Product name and model

•Product number

•Manufacturing measuring instrument license signs and numbers

•Test terminal mark

1.7 Warranty

Sourcetronic warrants this product to be free from defects in material and workmanship for a period of one year

from the date of shipment. During the warranty period, we will, at our option, either repair or replace any product

that proves to be defective.

1.8 Limitation of Warranty

This warranty does not apply to defects resulting from product modification without our express written consent,

or misuse of any product or part. This warranty also does not apply to fuses, software, or problems arising from

normal wear or failure to follow instructions.

THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING ANY

IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR USE. THE REMEDIES

PROVIDED HEREIN ARE BUYER’S SOLE AND EXCLUSIVE REMEDIES.

NEITHER SOURCETRONIC NOR ANY OF ITS EMPLOYEES SHALL BE LIABLE FOR ANY DIRECT,

INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OF ITS

INSTRUMENTS AND SOFTWARE EVEN IF SOURCETRONIC HAS BEEN ADVISED IN ADVANCE OF THE

POSSIBILITY OF SUCH DAMAGES. SUCH EXCLUDED DAMAGES SHALL INCLUDE, BUT ARE NOT

LIMITED TO: COSTS OF REMOVAL AND INSTALLATION, LOSSES SUSTAINED AS THE RESULT OF

INJURY TO ANY PERSON, OR DAMAGE TO PROPERTY.

[1]. For DC: The technical specifications are valid when the instrument has preheated for 60 minutes, the

integration time is set to 10 or 100 NPLC, and auto zero is enabled. For AC: The technical specifications are valid

after 60 minutes of preheating, slowAC filtering, and sine wave.

[2]. Outside the range of TCAL ± 5 °C, the temperature coefficient is increased by 1 for every 1 degree Celsius

change.

[3]. Relevant calibration standards.

[4]. The smallest data change that can be displayed, i.e. the value of the least significant digit.

[5]. Full-scale accuracy, there is need to perform NULL (clearing) operation in order to get better accuracy.

[6]. DC 1000V, AC 750V, AC current 3Aand DC current 3Acan only test 5% of the overrange.

[7]. When measuring resistance, it is better to use shielded line test when the resistance is greater than 100kΩ.

Because the intersecting magnetic field generates an induced current, and a large resistor has a relatively small test

current, the signal-to-noise ratio will be small and the test will be unstable.

[8]. Specifications are applicable to 4-wire or 2-wire resistance measurements. When zero clearing is not activated,

the 2-wire resistance measurement will introduce an additional error of 0.2Ω.

[9]. Specifications are valid when the sine wave input is >0.3% of the range and greater than 1mVrms. The

750-ACV range is limited to the 8 x Volt–Hz range.

[10]. Low Frequency Performance: three filter settings are available: 3 Hz, 20 Hz, 200 Hz. The frequency above

the filter setting is specified and no additional errors will occur.

[11]. Specifications are valid when sine wave input >1% range and >10μA AC. The 10A range is only available on

the front connector.

[12]. Specifications are applicable to the voltage measured at the input terminal. The 1 mA test current is a typical

value.A change in the current source will cause a change in the voltage drop across the diode junction.

[13]. Unless otherwise stated, the specifications are valid when the instrument has warmed up for 60 minutes and

has a sine wave input. Specifications apply to 1s strobe time (7 digits). The signal needs to be greater than 10% of

the selected range.

[14]. This is applicable when the sine and square wave are input larger than 100 mV. For a 10 mV to 100 mV

input, multiply the % of the reading error by 10.

[15]. High-frequency signals have serious attenuation in the latter stage, so the input voltage of the test signal

should be relatively large. The test signal is 1V-1MHz, and the input signal is preferably greater than 50% of the

range.

[16]. The square wave input is specified as 10 Hz-300 kHz.
