This meter is for you, If you repair switch-mode power supplies, high voltage circuits stages in: TV receivers, computer monitors, photocopying/fax machines, vintage radios, personal computers, gaming computers, motherboard recap service or similar equipment, and/or if you need to measure very low values of resistance, this meter can save you lots of time and aggravation... why?? Simply because the loss of time, with each repair *, is very low, for all faults that involve having to measure the electrolytic capacitors, this device measures them right in the circuit, and this becomes very fast even if that circuit has many capacitors. Thus much repair time with the easy cases, will be much more time available to concentrate on the most difficult ones , greatly increasing the profitability of your repairs.
This device measures an aspect of electrolytic capacitor performance which is very important, but normally very difficult to check: the equivalent series resistance, or ‘ESR’, (cause a catastrophic failure in circuit, if ‘ESR’ value raises in one or more electros around) ESR is not possible to measure with common capacity checker.
*more than 90% of equipment malfunction is due to flaws in electrolytic capacitors
All you could do with this meter:
-It quickly and easily identify defective electrolytic capacitors from 1uF to 1 Farad or more
while they were still in circuit, (or outside if need) by checking ESR value in Ohms
-Check resistance values from 0,01 ohm to 99ohm with 1% accuracy and 0,01ohm resolution
-Check for short circuits PCB tracks, solder joints, cables
-Check for bad contacts in electric contacts/switches/Relays
-Wound your own precision/power resistors, for antique electronic devices or heating devices
-White meter also check physical condition of any kind of battery up to 24V 12Ah
single or multiple cells. Measurements could be taken with batteries connected to circuit or charging devices.
Able to measure battery, same price as black meter
