IMF-600A LCR
Component Bridge.
IMF-600A is a cost effective manual or
auto ranging
digital impedance measuring instrument that complements the basic DMM to complete
your test and measurement needs. With its low resistance measurement
capacity and Kelvin leads, the IMF-600A is invaluable for locating
PC board shorts.

Automatic measurement
for all functions is provided automatically with a 3½ digit display.
No balancing or manual operations are required.
Analog & digital outputs may be used to interface to comparators or
other devices.
4-Wire shielded Kelvin test terminals - short
circuit location ensures precision measurements even for very low
impedances like contact
or wire resistance and makes locating PC board short circuits an
easy task.

NOTES
* HSC Option High
sensitivity capacitance range option. 20 pF full scale; 0.01
pF resolution; 1.0 Vrms test signal; accuracy4 (±0.25% + 0.3
pF).
** HSL Option High sensitivity inductance range option. 20 μH
full scale; 0.01
μH resolution; 100 mA test signal; accuracy4 ±(0.25% + 0.5 μH).
1. Capacitance: Higher capacitance (>200 μF) may be measured on
the
inductance function by the following conversion: Series model
capacitance
C=-2.533 x 10-8 /L.
2. Resistance: Higher resistance (>2 MΩ) may be measured on the
conductance
function Range 1: R (in ohms) = 1/G (in siemens).
3. Dissipation (D or 1/Q): Obtain D values by pressing D button.
Values greater
than 1.999 may be computed as follows:
D= G/2πfc = 1.592 G'/C'
Q=2πfL/R = 0.628 L'/R'
where G', C', L', and R' are in counts on the same range.
4. Accuracy: After correction for test lead zero reading; 15°C -
35°C; C, L, G, or
R readings are in absolute counts; ignore decimal point.
|
Test Conditions:
1. After correction for test lead zero reading.
2. After 10 minute warm up.
3. Between 15°C and 35°C.
Test Frequency: 1 kHz ±1%.
Measurement Rate: 2.5 measurements per second.
Analog Outputs: Impedance quantity and dissipation D are
simultaneously
available at the rear panel, scaled at 1 V/1000 counts;
accuracy: ±(0.25% of display
+ 1 mV).
Digital Output (Optional): 3-1/2 digit, BCD, for data and 3 bits
for range; TTL,
positive true.
Current Output (Optional): 4-20 mA corresponding to 0-2000
counts of display.
Input Protection: Diode and resistor discharge network.
External dc Bias: Up to 100 V, floating, may be applied across a
capacitive
component through screw terminals on the rear panel terminal
strip; 0.1 A
maximum.
