Power switch: Turns the power to the instrument ON or OFF. Data Interface: connect the data processing apparatus, such as PASCO interface. Current Range switch: Sets the current range for the instrument’s current amplifier (10-8 to 10-13 A). Signal switch: Sets the signal to CALIBRATION or MEASURE. Current Adjust: Sets the current through the instrument to zero. Ammeter: Displays the current. Input Signal: Input current signal.
Current range: 10-8~10-13 A, in six ranges, 3.5 Digit Display; Zero drift: ≤ ±1% of full range reading
Wide-range voltage power supply design, All of the power supplies have 110/220 input voltage switch, suitable for most of countries.
