Resistance / Volume Meter

Model 152-1

Model 152-1 resistance / Volume METER

The Trek Model 152-1 Resistance/Volume Meter is designed to precisely measure surface or volume resistance on a wide variety of conductive, dissipative, and insulative materials. The Model 152-1 employs a measurement technique which conforms to several ANSI/ESD Association standards for measuring surface resistance, resistivity, and volume resistance including STM2.1 for garments, STM4.1 for work surfaces, STM 7.1 for flooring, STM11.11 for planar materials, STM11.12 for volume resistance [IEC 61340-2-3] and STM11.13 two point resistance measurement. A variety of measuring probe electrode configurations are available for making surface resistance measurements, volume resistance measurements or used for surface resistivity meter calculations.

The Model 152-1 features exceptional measurement accuracy and wide measurement ranges of 103 to 1013 ohms using point-to-point probes or the two-point resistance probe for small surface measurements. The probes are purchased separately. Measured resistance values are clearly displayed on a high-contrast LCD display using scientific notation.

The electrode test voltage for the measurement probe(s) is switch selectable for 10 V or 100 V operation to conform to the individual requirements of the ANSI/ESD Association standards and testing conditions. The selected test voltage is indicated on the LCD display. The Model 152-1 is light-weight and portable, and can be operated from internal batteries or connected to an AC line power source using a battery eliminator.

152-1 Walking Test Adapter

• The Walking Test Adapter Kit [CN 1K039 ] for the Models 152 Resistance Meter and
  152-1 Resistance/Volume Meter allows analysis of resistance levels on the human body.

  The resistance of a person to ground in an electronic environment can be measured with the Trek Walking Test Adapter. This test provides measurement data of actual resistance on a person in multiple locations. This test ensures ESD safe practices, such as STM 97.1 "Body System to Ground" resistance measurements, are being implemented properly and that proper resistance is being maintained.
