Hioki SM-8200 Super Megohmmeter Series

• Digital numeric readout with virtual analog display.
• Easy-to-use combined digital-analog models. Timer, comparator, remote start and command functions included as standard features to support new applications.
• Many safety-enhancing features

Display Features

1. Clear, three-mode liquid crystal display
   
   - Bright LCD simultaneously displays data in three modes: quasi-bar-graph, virtual needle and numeric values.
    
2. Clear graduated scale and precise data reading
   
   - The one-line graduated scale is always visible, and scales automatically according to the selected measurement voltage. Data is held on the display after measuring, so there is no hurry to read it.
   - The numeric readout displays measured values at maximum resolution.
    
3. Enhanced response speed and reliability
   
   - Reliability is enhanced because, unlike analog meters, the LCD has no moving parts, and the virtual needle responds seven times faster than a mechanical needle. Installation in automated systems is supported.
    

Usability Features

1. Timer function included as a standard feature
   
   - The need for counting complicated measurement time (by stopwatch) is eliminated. Timer settings are retained in internal memory even when power is turned off.
    
2. Comparator functions included as a standard feature
   
   - Easy-to-use GO/NO-GO (Pass/Fail) decisions
   - NO-GO (Fail) decisions can be indicated by an alarm sound simultaneously with contact output.
   - Comparator settings are retained even when power is turned off.
    
3. Remote Start function included as a standard feature
   
   - Measurement can be started hands-free, using a foot-switch or trigger signal.
    
4. Function to prevent unintentional start
   
   - 16% lighter and 22% more compact than previous models.
   - The small attached stand makes operation even easier: panel buttons are easy to press and the display is easy to see.

Safety Features

1. Measurement is disabled unless the measurement leads are connected.
   
   - A shock hazard can occur if a measurement probe is inadvertently disconnected or pulled out while high voltage is being output during measurement.
   - This danger can be even greater if the black measurement probe is disconnected.
   - To ensure safety even when the black probe is disconnected, a measurement lead detection system is incorporated at the probe receptacles.
    
2. Interlock(HV-EN)provided as a standard feature
   
   - The HV-EN (interlock) function is linked with the foot-switch, open/close switch on the test jig and contact signal from an automated testing machine, so that measurement voltage is applied only when conditions are safe.
    
3. Measurement stops in a discharged state
   
   - When measurement is finished or aborted by switch action, the red and black terminals are discharged through 100 kΩ. This results in safer measurements by reducing the possibility of electric shock accidents from residual charge on capacitive DUTs.
   - When measurement is intentionally aborted, measurement voltage is shut off in about 0.1 second.
    
4. Function to prevent unintentional start
   
   - To avoid electric shock accidents in the event that the Start button is accidentally pressed when the DUT is not securely connected, the Start button must be held for at least one-half second before measurement starts.
    

Computer-Friendly Features

1. RS-232C included as a standard feature
   
    - A computer can be connected via RS-232C serial interface.

Function Expanding Features

1. An abundance of electrode types
   
    - All models support a wide variety of electrodes.
    
2. Special-purpose options enhance functionality
   
   - Special-purpose options include 1/R DC output, resistivity-proportional DC output, guard tips and alarm devices (Except for analog Model SM-8216) to enhance functionality.
   
   - Except for analog Model SM-8216
   
   - When switching between 100 V/120 V and 220 V/240 V supply voltage, an internal fuse must be changed. Please contact HIOKI or your nearest HIOKI distributor.
    

SM-8200 Super Megohmmeter Series

These models include both digital numeric and virtual analog level displays. Support for a broad range of high-applied-voltage and high resistance measurements.

SM-8213

The SM-8213 is ideal for insulation measurements of modern low-voltage electronic components. Easy-to-see simultaneous digital numeric and analog graduated scale displays. The maximum 50 mA current capability, which is the highest in this series, provides stable measurements of even high-value capacitors. To support measurement by computer, communication functions via RS-232C are included as a standard feature.

SM-8215

The SM-8215 is a basic insulation meter that carries on our company’s tradition of ultra-high insulation meters. It is used in various fields including electronic components and materials, and for insulation measurements on completed electrical products. The liquid crystal display includes both easy-to-read digital and intuitive analog level indicators. Convenient standard features include timer, comparator, remote start and Interlock(HV-EN) functions. Measures time characteristic and voltage characteristic of insulators. To support measurement by computer, communication functions via RS-232C are included as a standard feature.

SM-8220

The SM-8220 is a top-of-the-line super megohmmeter that can measure up to 2 x 1016Ω (at 1,000 V). The combined digital and analog display is the latest evolutionary step combining our line of super megohmmeters with the newest technology. This powerful super megohmmeter handles a variety of insulation measurements, from those requiring low to high measurement voltages and measuring from low to ultra-high resistance. Convenient standard features include timer, comparator, remote start and Interlock(HV-EN) functions. These enable safer and more reliable measurement of volume and surface resistivity using flat sample text fixtures (such as the SME-8310). RS-232C communication functions required for measurement by computer are included as a standard feature.
