Blue ESR
Tester
Ever needed to test high value
electrolytic capacitors in power
supplies? This kit allows you to test
the equivalent series resistance of
capacitors greater than 1uF in value.
Its a well known problem that caps in
power supplies of plasma televisions for
instance dry out as time passes and even
though the value of the cap is correct
the ESR isn't, resulting in problems in
operation.
Specifications:
*Measurement range: 0.01 to 99 ohms,
auto-ranging.
*Peak voltage across capacitor under
test @ full scale: 100mV.
*Update speed: 4 readings/second.
*Power supply: 9 volt battery (not
included).
*Controls: Single push button for power
on/off and zero.
*Dimensions: 5.75x3.5x1 inches
(147x86x24mm).
Features:
*Tests electrolytics in circuit, & test
leads are non-polarized.
*Test lead resistance compensation.
*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.
*Chart of good capacitor ESRs on the
front panel.
