NICE Little Display!

Reviewer: from Sebring, FL

PROs: Nice little meter w/ easy to read back-lit display. It stores the Battery/Voltage Type so the meter can be switched off when not being used. Paired up with a 1551-KBK BLACK ABS BOX, 3.15" X 1.57" X 0.8" plastic enclosure and some Black/Red Test Leads it makes a great little portable monitor. Just don't forget to set the battery/Voltage type at power up.

CONs: The only drawback is that it takes the monitor 3-5 seconds to stabilize on a reading. But for the price who cares!

It works with Lithium Iron, also!

Reviewer: from Hilo, HI

The instruction sheet has modes for lead acid batteries (P) and Lithium Ion cells (C). The meter actually has a third mode (F) for Lithium Iron Phosphate batteries. I discovered this by experiment as I was using a lithium Iron Phosphate battery. It works great!

Perfect little battery display

Reviewer: from York, PA

Mounted this in the back window of a modified New Bright Hummer, which has a 12V 4AH SLA battery running it. It came up for 12V as soon as It saw power. Perfect for this application!

Nice meter but some things to remember

Reviewer: from Los Angeles

It works but the data sheet is not totally correct. Another reviewer talks
about a 3rd choice for programing, (F) which Im going to try with my lithium iron phosphate battery. Just tried on 1F & seems to work. If anyone
knows what the F section is please respond.
