New Toy – PentaRef from

*New Toy – PentaRef from*

Found my cheap voltmeter was reading 9.57V for 9.600V. Opened it up and found an adjustment screw and now got it to read 9.60V.

I guess to be even more accurate, I need to lower the temperature to 70F/21C. Which means i need an air thermometer. Which would also need to be calibrated first. 😎

btw: Shipped this via USPS Priority Mail to Malaysia, and it arrived here within 8 days. Delivery confirmation reflected on USPS website.
