- Measures current down to 100pA
- All solid state and IC design
- Accepts either polarity of input
- Built-in computer interface
Nanoammeter, DNM-121-C2, a rugged and low cost instrument, is
a product of extensive R&D using high input impedance
integrated circuits. It has 4 decade ranges with 100% over-ranging.
The unit is suitable for current measurement in the range
of 100pA to 200µA. For the ease, readings are directly
obtained on a 3½ digit DPM. The instrument is capable
of accepting either polarity of the input current.
The very low leakage current of the input
stage combined with the high linearity fast response due to
high negative feedback enables accurate and easily reproducible
measurements. The instrument uses a FET input operational
amplifier that offers the very low input bias current, low
offset voltage, low drift and noise. These characteristics
have been fully utilized in the present Nanoammeter. This
operational amplifier is used in low level current to voltage
The unit can be connected
directly to a PC through an USB.SES-Data Access And Control is a built-in interface which gives user an option to store a value as displayed on the meter and tabulate it by the click of a button on the screen.Alternatively the data may be automatically entered into a table at user selectable interval.An 'END' button on the screen terminates the automatic tabulation.The Data stored in the table may then be displayed as a graph on the screen and may also be stored in an excel file for further processing.The software supplied with the unit is menu driven and simple to operate
This unit can also be connected to PC through an interface module SES-CAMM.SES-CAMM is computer aided module for connecting multiple subunits of experiments, such as Two Probe Setup,to same interface on a computer.This feature is particulary useful in making this model compatible with computerized versions of complete experiments from our company.
