Does anyone know the lowest value capacitor that the Blue ESR meter can reliably test?

Blue ESR Features:

• Supplied in kit form with Instructions & manual online
• Two foot leads made with super flexible test lead wire with 4mm banana plugs
• Test lead resistance compensation
• Resistance measurements from 0.01 Ohm to 10 Ohm.
• Automatic power off when reading is unchanged for 3 minutes
• Low battery voltage warning
• Easy-to-read, high brightness 0.5 inch (13mm) piercing blue LED display
• Easy to read chart of good capacitor ESRs on the front panel with capacitor voltage values from 10V-450V, 1->10,000uF capacitance
• Test ESR on polarized and non-polarized capacitors with the value of >1 uF
• Measures ESR for capacitors in circuit, ideal for PCB level de-bug
• Can also be used to test the low resistance grounding of ANSI/ESD S20.20, ANSI/ESD S6.1, ESD TR20.20 and compliance verification for grounding systems
• Detection of shorts on PCB's and shorted coils in transformers
• Assess health for alkaline and rechargeable batteries
• Operational down to 5.5v battery voltage, maximizes battery life
• Kits made in Silicon Valley California, USA

 

The results of ESR measurement with Blue2 ESR and LCR meter at 100kHz differ significantly in some cases.
