Hioki DSM-8542 - 4-Channel Ultra High Resistance/Ultra-Low Current Meter

The Hioki DSM-8542 measures capacitance and high insulation resistance quickly and accurately test for current with 0.1fA resolution. For practical measurement applications in semiconductor and electronic materials research, a broad range of voltage settings, high 0.1 fA resolution, automatic resistivity calculation, measurement data memory for large values, and histogram display of selected measurement results are included as standard features.

Fast measurement for improved productivity

•  
• Capacitive insulating materials are quickly charged by bulk charging terminals to 250 V (at 50 mA) or to 1,000 V (at 10 mA) using a high-capacity, low-noise power source
• The 100Ω input impedance remains constant regardless of measurement voltage.
• Measurement sampling time can be set from 2 to 300 ms to support high speed measurements.
• Measurement time is significantly shortened by a patented averaging method (optimization of average time of acceptance of measurement current, Japan Patent No. 3461937).
• The installed charging terminals and handler interface make system support easy
• Supports data collection on a PC
• Model DSM-8542 provides high-speed simultaneous measurements on up to four channels when used together with the optional, special-purpose PSU-8541 Power Supply Unit.
• Charging power supply PSU-8541 provides high and low-voltage channels: 10 V at 600 mA for low-voltage channels, and 250 V at 600 mA to 1,000 V at 120 mA for high-voltage channels, with excellent stability during low-voltage output.
• The PSU-8541 includes charging terminals for up to 20 channels

• Measures current flow with 0.1 fA resolution using any specified applied voltage from 0.1 V to 1,000 V in 0.1 V steps.

• Contact check function prevents false positive judgments due to poor contact with work
• Measurement sequence program ensures measurements are taken under the same conditions every time.
• When measured voltage differs from a preset voltage by more than 3%, a voltage check error notification is issued

• Use in combination with the optional SME-8310/8311 Flat Sample Test Fixtures, or with the optional SME-8330 Fluid Resistivity Cell to measure and automatically display surface resistivity or volume resistivity, respectively.
• Stores 1,000 measurement data points for searching and display
• Displays percentage and deviation from a reference value.
• Displays histogram of selected results.
• Select from up to ten types of measurement sequences according to the object to be measured.
• Displays the remaining time for each stage of a measurement sequence.
• Measurement settings are displayed together
