For low voltage from 5 to 100 V DC and charge current up to 50 mA
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.
Caractéristiques
Display Features
Clear, three-mode liquid crystal display- Bright LCD simultaneously displays data in three modes: quasi-bar-graph, virtual needle and numeric values.
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.
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
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.
Comparator functions included as a standard feature- Easy-to-use GO/NO-GO (Pass/Fail) decisionsNO-GO (Fail) decisions can be indicated by an alarm sound simultaneously with contact output.Comparator settings are retained even when power is turned off.
Remote Start function included as a standard feature- Measurement can be started hands-free, using a foot switch or trigger signal.
Compact and lightweight- 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.
