DESCRIPTION
The Micro-Ohmmeter Model 5600 performs reliable low resistance measurements with
test currents to 10 A and resolution to one micro-ohm.
The Model 5600 uses a four-wire Kelvin bridge method, which eliminates test lead
resistance for a measurement accuracy of 0.25%. A reverse polarity switch
compensates for the effect of DC voltage interference on the accuracy and permits
reading averaging. A built-in circuit filters against AC signals.
This instrument is housed in a sealed field case. Power is supplied by a long-life NiCad
battery with a built-in charger (110/220 V). The large, easy-to-read LCD is 18 mm high.
It displays the value of resistance, and indicates overrange and reversed connection of
measurement leads.
Four LEDs on the front panel indicate measurement faults (open circuit, blown fuse,
etc.); thermal protection; low battery and battery charging.
For operator safety and instrument protection, the micro-ohmmeter is fuse protected at
the inputs. Two fuses, accessible on the front panel, protect against stored energy in
inductive loads.
Enhanced internal circuitry protects against kickback when the current is shut off. A
built-in thermal switch protects the micro-ohmmeter against overheating on the 10 A
range when in continuous use.

BOARD MAINTENANCE AND REPAIR
1) Main Board – Operating Description:
a) ON-OFF
S1 switches ON or OFF.
At point (3) behind anti-bouncing Circuit) there is level 0 when switch is not
pressed, and levels 1 when switch is pressed.
Circuit Z5 is a dual D Flip Flop, its output (Q) takes in account the state of
input D (5) for each positive going clock pulse (3).
D input is connected with output Q, this means that Q changes (as well as Q)
at each positive going clock pulse; i.e. each time S1 is pressed.
Outputs Q and Q trigger opening and closing coils of the residual bi-stable
relay K1.

b) OSCILLATOR – SUPPLY
Oscillator is composed of Z8; R43; R44; C11
At point (8) there is a square wave frequency = 35 kHz which is supplied to Q6
and Q7, Q8 Darlington Amp Circuit causing transformer T1 to ring at its input.
Regulation is made by circuit Z9A, its inputs are connected on one side to
reference 2.5V (CR22 : LM336Z) and on the other side to bridge R49, R50 image
of voltage V2.
Supply Voltages:
c) LOW AND EXTINCTION DETECTIONS
Link R54; R55; R57 is calculated so as to get:
a) 2.5V on (11) when battery is on 5V
b) 2.5V on (10) when battery is on 4.5V
Case a): Voltage goes under 5V then Z9b changes to Vsat+. Oscillator Z6; C19;
R61 starts and triggers Q9 that makes LED CR23 flash.
Case b): Voltage goes under 4.5V then Z9C changes to Vsat+ and triggers
instrument extinction through CR11 acting directly on Q3. This stops the
instrument without Z5. To start the instrument press S1 twice (first pressing will
set back Z5 properly).

d) FAULT AND AUTOMATIC STOP
Detection is made at terminals C1 and C2.
When current circuit is not closed by a resistance to measure, then C1 is on
potential +Batt and C2 on potential –Batt.
As for measurement, there can be up to 2V between C1 and C2 on range 200 Ω
x 10 mA.
Whether level is >2V (R23; R24) there is no measurement, or at least a
resistance >> to range.
At point (15) there is VC1 C2 (rectification is necessary since measurement is
also possible in (-) and VC1 C2 can be positive or negative).
When opening circuit C1, C2, voltage at point (15) now becomes superior to R23
level; R24 and (16) change to +Vsat.
Diode CR17 lights on.
Signal (16) will trigger extinction timing control. Z4 is a 555 timer set in
monostable way its timing control is given by formula: t = -(R32 C5 x Ln 1/3) =
241s. (4mn) and triggers on falling edge of Trigger (2) input.
If a measurement is made before end of timing control (17) falls down to 0 and
modifies extinction forcing a level 1 on (23). On the contrary, timing control goes
normally and once finished it triggers extinction of the instrument.

Vref creation
A FET (Q1) is used to regulate reference.
Example: with range 200Ωand measurement = 200 Ω.

600 Ω
Input – of Z1 is on point (26) potential.
Z1 regulates in order to get e+ = e- (if Vs changes then VGS of Q1 changes, RdS
also changes as well as for current in section R8-R11).
So, if e+ = e-, this means that potential on point (27) is the same as potential on
point (26), that is to say that:
VR6 = VR8 = 100mV.
In fact R11 = R8 and iR11 = iR8 so VR11 = VR8 + 100mV = Ref.

Advantages of this system:
Vref voltage is the image of VR6 voltage and IR6 is the same as current in
measurement, so there will always be a reference proportional to current
whatever the state of battery. It prevents regulation of measurement current and
improves transitional responses (measure of self-induction resistance).

2) TROUBLESHOOTING:
Trouble when starting up the instrument:
•Check operation. Refer to section (a), page 9.
•Check that J2 is properly connected.
•Make sure there is no extinction signal interference through R34/C7. If necessary,
lift up R34. If there is interference, check the extinction signal on CRIO side or
CRII side in order to locate it.
Instrument may start up, but nothing operates from outside due to a supply
trouble ± V1; V2:
•First check reference voltage at CR22 terminals: VCR22 = 2.5V.
•Check oscillator gives out (8) signal.
•Check diodes CR17; 18; 21.
•Transistor Q8 can wear out quickly since it is frequently controlled.
•If the first three checking points are OK, then change Q8.
•Z9 may be out of order or not supplied.
Impossible Measurement (false):
•Check that the measuring chain is operating. First link with a strap and mass
in order to set measurement potential, then inject a signal on P1, P2.
Follow this signal all along the measuring chain and check the value of mid signals
with gain indicated at (section e, page 12).
•If the measuring chain operates properly, check the reference. Create a short
circuit between C1 and C2 to close back measurement circuit and check that VR1;
VR2; VR4 or VR6 (according to range) = VR8 = VR11.
Then look into Z1 or Q1
•If measuring chain and reference operates properly, look into Z14.
•Other possible cause: part of the measurement current is diverted into protection
board.
Trouble with ‘Fault’ signal:
•Check operation. Refer to section (d), page 11.
•If potential C1, C2 does not go up when opening C1, C2 circuit, this means that
Q202 on protection board is short-circuited and preventing potential from going up.
Therefore detection is impossible in these conditions.
Trouble with extinction timing control:
•Check operation. Refer to section (d), page 11.
•Extinction timing control is impossible if ‘Fault’ is out of order.
•To repair: timing control can be shortened connecting in parallel 470kΩand R32
for instance. You will get a timing control of approx. 10s.

FILE LOCATION: E.F. Disk - Manuals - Cal. Man. - Model 5600.DOC
10/27/99
Trouble with ‘low’ or extinction of ‘battery threshold’:
•Check operation. Refer to section (c), page 9.
•Check reference at CR22 terminals: VCR22 = 2.5V ± 0.1V.
•Disconnect J2 and inject a variable voltage (6 to 4V) on R54 (+) and R57 (-) in
order to check balancing of detection amplifiers.
•If levels are wrong, check values of bridge R54, R55, R57.
Comas:
•Check continuity through connector J1 which ensures connection between
principal board and commutation board.
Display:
No display on all ranges:
•Before looking into Z14 or D1, check that it is not a trouble with supply ± V1.
To check Z14: Display = V Measurement x 1000
V Reference
•Battery voltage good (> 6 V DC): Check + V1 and - V1 (6 V DC).
•Check relay K1 switch each time the ON/OFF switch is pressed.
1) Relay does not work: Z8, Z5 or Z15 defective.
2) Relay works: Q8, and maybe Q6, Q7.
Check resistor R25, 100 Ωand diode CR16 = 1.5 KE15V
± 6 V good: Z14 defective.
Display is lit but reading stays at one value:
•Be sure to check that the input of Z10 conforms to the schematic.
If not, add C041 and RV01 and remove diode CR03 and CR04.
•Check diode CR28 and CR30.
(Z10 is sometimes defective after CR28 has failed)
Adjustments impossible:
•Symmetry: Refer to R64 or Z12.
•Zero: Refer to VCR24 and VCR25 = 2.5V ± 0.1V.
Check if R76 is out of order.
•End of scale: Check if R98 is out or order.

SUPPLY BOARD
1) Operating:
a) Protections against overloads 110/220V
In case of error 100-200V, voltage at transformer secondary is exceeding zeners
conduction level, it triggers Q301 that closes itself. Secondary being short-
circuited, current in primary increases quickly, CTP RT301 overheats until it
opens itself, disconnecting main supply primary at the same time.
Processing delay: approx. 2 sec.
Wait until CTP is cold before using charger again.
b) Load
Once rectified and filtered, load current goes in battery through regulator Z301.
Current limit is defined by both Q302 and R303 to R306. (I = Vbe = 0.8A)
R
CR306 limits voltage +Batt in case of loading attempt with no battery. V limit = 9V.
CR304 keeps regulation steady even in case of disconnection to CR26 (signal
changes).
2) TROUBLESHOOTING:
•First check programming of main supply voltage (S301). In case of bad
programming, wait until CTP RT301 gets colder.
•Even if programming of voltage is right and CTP opens each time the instrument is
plugged in, check Q301 that may be short-circuited, or CR301 diodes or level is
not right (BZX 55 C 20V).
•If there is no more load current, make sure that the battery is working. If
necessary, replace the battery by a resistor (7.5Ω/5W) and check if charger is
operating.
•Make sure that CR304 is not disconnected.
•Check VR308 = 1.25V ± 0.05V. If not, change Z301.
•Load current value is: Ich = Vbe (Q302) That is to say = 0.8A
Req 303 to 306
HEAT SINK PLATE
1) Operating:
a) Principle
When overload occurs, once zeners conduction level is exceeded, triac transistor
is triggered and then puts itself into short-circuit, this way helping F1 or F2 fuse to
melt.

NOTE: A protection board out of order can produce troubles on measurement
board. If triac transistors are short-circuited, measurement current is diverted into
triac transistors and measurement result is false.
On the other hand, if triac transistors are short-circuited, detection ‘fault’ is
impossible (C1 and C2 on C-C), as well as extinction timing control.
Triac transistors can also be worn out and produce some current leakage.
Maximum leakage: 10µA under 2V, that is to say 0.1% of measurement current
on range 200Ω.
To check that protection board is not causing false measurement, unplug J4: S4,
S5, S6.
b) 10A Flow:
When commutator is on 10A, MOS-FET Q201 is supplied through R15/R28
letting in current flow in measurement section. The complete resistance of this
measurement section and the state of battery define value of measurement
current. RT = R1 + R401/402/403 + Rds Q201 + Cabling + Inter ~ 600mΩ.
Ι = Vbat ~ 10A nominal.
c) Thermal Protection:
When MOS FET temperature is too high (limited to 80°C) thermostat K401 closes
itself and stops Q201. Current cannot flow anymore, wait until thermostat starts
again, temperature of MOS FET must be 60°C so that current can resume.
NOTE: Thermal protection only occurs on ranges 10A 2000µΩand does not
prevent the other ranges from operating.
2) TROUBLESHOOTING:
Protection:
•Check connections to principal board.
•Check trigger diodes value and that they are not short-circuited.
•Change triac transistors.
10A Flow:
•Check to see that the thermostat is not close to ambient temperature, preventing
the current from flowing.
•Check connections to principal board.
