292A 精密型砝码式表面阻抗计

• Liquid Crystal Display (LCD): A 3.5 digit 9/16” high, liquid crystal display provides easy to read measurements directly from the meter. No interpretations or calculations are required.
• LED Displays: Surface resistance exponents are displayed via 12 light emitting diodes (< 103 - >1012). LEDs are color coded for quick check recognition: Five additional Function LEDs identify the measurement taken when lit.
• Auto/10 Volt Hold Test Range Voltage Button: When in the “up” or Auto position, during resistance testing, the meter automatically switches to the correct voltage for the resistance range. When in the “down” or 10 Volt Hold position automatic voltage selection is overridden and the test is performed at 10 Volts regardless of resistance level. An LED illuminates to note selected voltage.
• Test Push Button: Activates electrical power to the meter.
• Quick Check Button: When set to FULL, the meter will cycle through the 15 second electrification period that displays the temperature and relative humidity before the surface resistance mantissa is displayed.
* When set to QUICK, the meter will skip the 15
seconds and immediately display the surface
resistance mantissa.
• Ambient Temperature, Relative Humidity and Surface Resistance Mantissa Measurement: When the test button is pressed and the meter is set to FULL test mode, following displays in sequence:
• Temperature in degress F (+/- 50)
• Temperature in degrees C (+/- 30)
• Relative Humidity as a percentage (+/- 10 integers)
• Surface Resistance Mantissa (with exponent displayed via LED, measurement expressed in ohms.)
型号 : Monroe 292A

Monroe Model 292A Digital Surface Resistance Test Kit is a portable, versatile, instrument designed to accurately measure resistance between two points (Rtt), surface to ground (Rtg), and surface resistivity in accordance with ANSI/ESD Association standard S-4.1. In addition, the meter measures ambient temperature and relative humidity.
