DVM Current Meter adapter, 1 nano amp to 300 milli amps DVM adapter:
$249.99
The product is a DVM nano micro & milliAmpere Test Meter Adapter, designed to work with any DVM (Digital Voltmeter). It can measure a electrical current range from 1 nano amp to 300 milliamps. This adapter allows for precise measurement of current in a small range, working with any DVM and making it useful for various testing and inspection purposes in industrial and other settings. It is a unit quantity item that is specifically designed for nano micro & milli ammeter current measurement applications.
No digital muti-meter is accurate at measuring DC or AC current in low voltage circuits. The closer to full scale you get and the lower your circuit supply voltage gets, the more inaccurate your current measurement gets.
TheBurden Voltagecan affect practical circuit measurements with multimeters.
To verify make a simple test with your DMM.
·Try to measure 190 mA on the 200mA current range
·Read your DMM manual to find out your meters' “Burden Voltage”. Fluke 87 has1.8mV/mA
·Do simple math to see what voltage Meter is dropping (i.e. 190mA x 1.8mV/mA =0.342 V)

NuMeter
A micro-‘current meter’ adapter for multimeters
Testing nA, micro-Amps and milli-Amp currents
with precision NuMeter
Testing withNuMeter is fairly straightforward.
Always connect "current input" in series with the testing circuit.
You can check your NuMeter accuracy (see below)
You will need a power supply and some suitable resistors
(or decade resistance box), and your DVM.
- Switch NuMeter to BATT CHECK mode from OFF .
The LED should light within 0.2 seconds.
- Switch to ON mode and the LED should turn off & will be ready for current measurements.
- Connect the Voltage Output terminal to your
- Set DVM to the mV DC range.
- With nothing connected to NuMeter you should measure
zero on all three current ranges.
- Selecta resistor suitable for each range to give
you a decent current level around half of your
meters full scale.
e.g. for a 5V supply, use a 47 ohm, 1W & shall read 106mA,
with 47 K-ohm shall read 106µA, & five 10 Meg resistor in series shall read 100nA.
- Connect your test resistor in series with your
7.supply and with the NuMeter' s "Current Input" terminals.
Note: Ensure that you have the correct range
selected before switching on your supply voltage,
you don’t want to blow any shunt resistors in your NuMeter!
for the values mentioned above.
8.Don’t forget to switch OFF when you are
