| GPIB | General-purpose interface bus (GPIB) is designed to connect computers, peripherals and laboratory instruments so that data and control information can pass between them. GPIB is also known as IEEE 488 or HPIB. It is electrically equivalent to the IEC 625 bus. | ||
| RS232 | RS232 or ANSI 232 is used for serial communications between instruments and computers. | ||
| Printer Port | Devices include a connector or port that is designed to interface with a printer. Usually, the printer port is a parallel interface. | ||
| Scanner Port | Devices include a connector or port that is designed to interface with a scanner. | ||

| Resistance Range | Resistance range is the range of electrical resistance that devices can measure. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| DC Current | This is the DC output current. The type of test determines the level of current that is supplied. For example, hipot testing usually produces a very low current output. | ||

| Features | |||
| Your choices are... | |||
| Remote Control | A remote control allows the instrument to be controlled by another instrument or computer. | ||
| Built-in Calibration | Built-in calibration allows an operator to calibrate the instrument without removing it from the test location. | ||
| Warning Indicator Light | Warning indicator lights are lamps that indicate a pass/fail condition. Sometimes, they are complemented by an audible alarm. | ||
| PLC Interface | In automated testing environments, devices are often interfaced with a programmable logic controller (PLC). | ||
| Buzzer or Annunciator | Buzzers and annuciators alert operators to test conditions that may have failed. | ||
| Multiple Test Setup | Testing devices can be programmed to perform more than one test in succession. | ||
| Rapid Cutoff | Rapid cutoff protects the output circuit from excessively high levels of voltage or current that could damage the instrument. | ||
| Selectable Output Frequency | Users can select the output frequency. Typically there are two choices: 50 Hz and 60 Hz. | ||
| Front Panel Lockout | Front panel lockouts allow users to password protect instruments to prevent adjustments during testing. Some manufacturers call this tamper-proof operation. | ||
| Memory / Storage | Test information is stored in memory. | ||
| Clamp-On | Devices have a clamp-on loop that is used to measure the resistance of ground rods. | ||
| Auto-Ranging | Devices automatically select the optimum measuring range. | ||
| Audible Alarms | Devices have audible alarms to alert users when thresholds are reached. Often, these thresholds are programmed by users. | ||

| CE Conformity Marks | CE conformity marks indicate that products comply with the requirements of relevant European health, safety, and environmental protection directives. All electrical and electronic equipment shipped to Europe must have the CE Mark to indicate that devices meet both the "General Product Safety Directive" and the "Electromagnetic Compatibility Directive". CE is an abbreviation of the French phrase "Conformité Européene", which means "European Conformity". | ||
| CSA | The CSA Mark may appear alone or with indicators. If it appears alone, it means that the product is certified for the Canadian market, to the applicable Canadian standards. If this Mark appears with the indicator "C and US" or "NRTL/C" it means that the product is certified for both the U.S. and Canadian markets, to the applicable U.S. and Canadian standards. | ||
| IEC | The International Electrotechnical Commission (IEC) is the authoritative worldwide body responsible for developing consensus global standards in the electrotechnical field. IEC is dedicated to the harmonization and voluntary adoption of these standards, supporting the transfer of Electrotechnology, assisting certification and promoting international trade. Since 1906, IEC has served the world's electrical industry, developing international standards to promote quality, safety, performance, reproducibility, and environmental compatibility of materials, products, and systems. It has also published standards for the electronics and telecommunications industries. The IEC's present membership of 51 countries includes most major trading nations. IEC standards are widely adopted as the basis of national or regional electrotechnical standards, and are often quoted in manufacturers' specifications and by users when calling for tenders. Over 2000 standards cover virtually every topic of Electrotechnology from acoustics, to medical devices, to insulating materials, to aircraft, to nuclear instruments. The IEC's membership consists of the electrotechnical standards organizations from each participating nation. The American National Standards Institute (ANSI) represents the United States. | ||
| IPC | The Institute for Interconnecting and Packaging electronic Circuits (IPC) a global trade association that includes designers, board manufacturers, assembly companies, suppliers, and original equipment manufacturers (OEMs). IPC is a member-driven organization and leading source for industry standards, training, market research and public policy advocacy. | ||
| TÜV Rheinland (US, C, US & C) | TÜV Rheinland/Berlin-Brandenburg provides international approvals services as they relate to product safety. Products certified by TÜV Rheinland for the US market are identified by the TUVus certification mark. TÜV Rheinland of North America is also established as a Certification Organization in Canada. When the TUVus mark is coupled with the cTUV mark, the product is certified compliant for both the US and Canadian markets. | ||
| UL Listing Mark | The UL listing mark denotes that samples of a product meet the safety requirements of Underwriters Laboratories (UL). These requirements are mostly based on UL's published standards for safety. | ||
