BLUE Line ESR
Redesign von BLUE METER ESR / LOW OHM METER
Einführung
An easy-to-use meter that can repair electronic equip-
ment, i. amplifi ers, televisions, monitors, signifi can-
tly accelerated. It makes it easy and quick to identify
a damaged electrolytic capacitor without having
to desolder it from the PCB board. As a result, you
can quickly repair a device without having any exper-
tise in electronics. With BLUE LINE ESR you save
a lot of time and money. It is completely assembled and
calibrated. When used properly, it will be reliable for
many years.
A completely new design based on a 32-bit mi-
crocontroller that:
• reduces energy consumption (the meter requires only
2 AA batteries 1.5V)
• temperature compensation allows
• extends the measuring range up to 108 ohms (the
3-digit display)
Features include:
• In-circuit testing of electrolytic capacitors
• Test lead resistance zeroing
• Non-polarized test leads
• Easy-to-read, high brightness blue LED display
• Automatic power off when reading is unchanged for 3 minutes
• Battery life (about 20h)
• The high-power diodes built into the input circuit prevent the meter from being damaged by the con-
nection of a charged capacitor
Making a Measurement:
1. Switch on the meter by pressing the
button. Symbol “---” appears on the display to indicate that the
meter is on and test leads are separated (or disconnected).
2. Insert the plugs of the test leads into their sockets.
3. Hold the test probes tightly together* and press the
button again to start zeroeing procedure. In the
result the 0.00 reading will appear on the display.
* To provide the best accuracy of measurement ESR, the probes should be as short as possible (less than 1m) and
have a resistance below 0.5Ω. If the reading is higher than 0.68 it is not possible to perform zeroing resistance.
