ER-1E Four-wire Lithium Battery Internal Resistance Tester High-precise Nickel-metal Hydride Button Batteries Alternating Current Milliohm Meter 0.01-200ohm Measurement Ranges

Features:

Four lines 1KhzAC sine battery internal resistance meter with 0.01 milliohm-200ohm ranges. 

It can be used to measure leadacid, lithium ion, lithium polymer, lithium iron phosphate, alkaline, dry battery, ni-mh, nickel cadmium, button battery, etc..

Equipped with low resistance mode, short press the power on button to turn on the low resistance function, measure 0.30-0.50 milliohm internal resistance.

Large LCD display, the built-in battery voltage, tested voltage and internal resistance displays on the same screen, the ranges can be changed manually and automatically.

Internal resistance manual switchable ranges: 20mr, 200mr, 2r, 20r, 200r.

Voltage measurement ranges: ±10V and +30V two gears switchable.

It can be updated 4 times every second, 1 second to stable ranges.

The reading can also be locked, and with battery sorting function.

Built in lithium battery, USB rechargeable, 400mAh recharging current, the screen shows the battery voltage lower than 3.5V please recharge it.

Automatic shutdown time can be set, and the backlight brightness can be adjusted according to your usage, power saving.

It can be manual calibrated with precise resistor and precise adjustable powersupply, no standard voltage resistance value is required.

The accessories of this instrument are probes, Kelvin clip, 4-wire shelf available, can be selected according to needs, to meet the different requirements of users.

Note: 

Please don't test the battery over 30V, do not test the direct current powersupply and regulated powersupply, there is a risk of burnout.
