The 2000 Series Railroad Testers are designed to perform standard maintenance tasks (using Volts, Ohms, and Amps measurements) as well as specialized tasks requiring measurements on railroad coding equipment. The 2000 Series is compatible with older test technologies and offers test features not found on earlier test sets.

- Upon order placement, please provide the company name that should appear on the certificate. Without this information, we will not be able to provide a certificate of calibration.
Fewer jacks, more ranges, and a logical front panel layout all contribute to the 2000 Series' ease of use. A precision multi-turn Ohms Adjust Control facilitates accurate resistance measurements. Also, the measurement of relay contact On Time has been simplified and expanded requiring no adjustments. Code Parameter measurements have been made simpler and more accurate. It is no longer necessary to count pointer swings to measure On Time. It can be measured on live signals as well as relay contacts. Peak Levels can be determined quickly and automatically, and adjustments to the code equipment peak level can be made without constantly readjusting the Test Set. Some models offer Cab filters, allowing measurement of the individual Cab Signal carrier frequencies, whether coded or un-coded. All 2000 Series Railroad Testers include: test leads, padded water repellent carrying case, shoulder Strap, and batteries.

Q: What exactly is meant by the term "Dry Contact" in the context of test equipment, and how does it differ from other contacts?
A: At its core, "dry contact" refers to a relay contact that does not supply voltage when activated. It acts as a pure switch, opening or closing a circuit without introducing any external voltage. On the other hand, a "wet contact" will provide voltage when activated.
In practical terms, think of a dry contact like a light switch. When you flip the switch, it doesn't supply power on its own; it simply allows the pre-existing power in the circuit to flow (or stops it from flowing). A wet contact, however, is akin to a switch that also supplies power when turned on.
It's essential to understand this distinction, especially in applications where the external equipment has its own power source. Using the wrong contact type could lead to undesired results or even damage to the equipment.
