Description
The DMMCheck Plus is a battery powered instrument that checks seven important functions on a DMM: AC and DC Voltage, AC and DC current, Resistance, Frequency, and Duty Cycle. If you have a DVM or DMM that has questionable accuracy, the DMMCheck Plus can give you the confidence you need before relying on your test equipment. A 9 volt battery pack is included.
The DMMCheck Plus provides the following test circuits:
- Resistance: 100Ω / 1.00 kΩ / 10.0 kΩ / 100 kΩ (±0.1%, 10ppm precision resistors)
- DC voltage: 5V, ± 0.007% voltage reference
- DC current: 1mA, ±0.1% current source
- AC voltage: 5V RMS, bipolar (+5V, -5V) square wave, ±0.1% voltage source
- AC current: 1mA RMS, ±0.2% current source
- Frequency: 100 Hz / 10 kHz, ±0.02% signal source
- Duty Cycle: 100Hz, 5V RMS, signal source has 50% ± 0.05% duty cycle
- Capacitance (with pre-installed L/C option): 1nF / 10nF / 100nF / 1µF (±0,05% precision capacitors)
- Inductance (with pre-installed L/C option): 1µH / 10µH / 100µH / 1mH (±0,05%)
Specifications
- AC/DC voltage output, output resistance : 25Ω, typical*
- Current drain: 5mA, typical*
- Dimensions (no enclosure) : 63,5 x 55,9 mm
- Dimensions (with enclosure): 76 x 76 x 54mm
- Battery: Alkaline 9V block (included)
*) The DMMCheck Plus is calibrated with a 10MΩ load connected to the voltage output terminals when measuring DC; 10MΩ is the typical input resistance of most DMMs when measuring DC Volts. A 1MΩ load is used for AC Volts.
