The following safety information must be observed to ensure maximum personal safety during the
operation of this tester.
To avoid electric shock when replacing the batteries first disconnect the leads from the object
to be measured.
When replacing the batteries, do not install old batteries with new ones and do not mix
different types of batteries.
Check the battery polarity carefully when inserting the batteries.
Do not short circuit used batteries, disassemble them, or throw them in a fire. Doing so may
cause the batteries to explode.
Be sure to dispose of used batteries properly:
•Remove the battery cover
•Insert the batteries into the battery compartment
WARNING!
Do not attempt to measure DC voltage exceeding 60V. Do not attempt to measure AC voltages.
This could result in injury or damage to the unit.
Do not attempt to measure the voltage of a generator. This would result in an AC voltage being
applied to the voltage generating output terminals, which is dangerous.
After measuring a high voltage battery, before continuing to measure a low voltage battery first
short the measurement leads together. This will discharge the DC elimination capacitor which is
connected across the leads. Otherwise an excess voltage may applied to the load voltage battery.

1. Connect the RED test lead to the SOURCE + terminal.
Connect the BLACK test lead to the SOURCE - terminal.
Connect the YELLOW test lead to the SENSE + terminal.
Connect the BLUE test lead to the SENSE - terminal.
2. Connect the BLUE miniature plug of the clip-type test lead with temperature sensors to the
TEMP. SENSOR jack.
3. Rotate the resistance range switch to the desired position.
4. Carry out the zero adjustment (for details, see the Zero Adjust Function section).
5. Connect the red clip (probe) of the test lead to the positive (+) side of the battery to be tested
and black clip (probe) to the negative (-) side.
The outer shield conductors of the clip (probe) are connected to the SOURCE terminals, and
the inner clip (probe) conductors are connected to the SENSE terminals. When contacting the
clips (probe) with the battery terminals, press the inter clip (probe) conductors so they are
pushed inside, and all of the SOURCE and SENSE conductors make good contact.
6. Read the battery internal resistance, DC voltage and temperature directly from the display.
When using the clip type test lead, the temperature sensor is detected, and the temperature
is automatically displayed.
7. Press the key for 2 seconds to change the displayed temperature unit.
NOTE: When the measured DC voltage or battery internal resistance value is overload, ‘OL’ is
displayed. A resistance indication ‘- - - -‘ means the AC test current fault that the measurement
could not be made, because there is a break in the test lead circuit, or the leads are not
making good contact with the object being measured, or if its resistance is extremely large
compared with the measurement range.

The zero-adjustment function is to zero the range of resistance. The reading during zero adjustment
will be taken as zero and will be used to calibrate subsequent measurements.
Using the supplied zero-adjustment board, zero-adjustment can be carried out according to the AC
four terminal method.
1. Rotate the resistance range switch to the desired position.
2. Press the key to turn on the zero-adjustment function on, the is displayed be
flashing.
3. As shown in the image below, push the pin-type test leads onto two holes in the zero-
adjustment board. Choose holes symmetrically on both sides of the centre screw, so that the
distance between the leads is about equal to the distance when measuring the battery
terminals.
4. When the resistance reading is lower than 200 digits and stable, the zero-adjustment is
automatically carried out, the will stop flashing and the beeper sound will stop.
5. Remove the pin-type test leads from the zero adjust board and start the measurement,
connect the leads to the battery to be tested.
6. Press the key to exit this function.
NOTE: if the terminal spacing of the battery to be measured is larger than the zero-adjustment
board, use the outer most holes for adjustment. The zero-adjustment is valid for the currently
selected range only, as long as the power remains on. Powering on the meter will reset all
zero-adjustment values.

Short the SOURCE and SENSE of the clip type test lead with the temperature sensor together as shown
in the image below:
Press the key, appears on the display and the display is locked. Press the key again to
exit.
1. Press the key for 2 seconds to start the auto-hold function, appears on the
display.
2. The meter holds the reading on the display until it detects a new stable reading. Then the
meter beeps and displays the new reading. When the measured reading is stable,
appears on the display.
3. Press the key again to exit.
If the resistance measurement value is unstable, this can be corrected with the moving average
function.
1. Press and hold down the key, then rotate the resistance range switch to any range to turn
on the meter, to samples select mode, ‘SET’ appears on the display.
2. Press / key to select the desired ‘OFF (no average)’, ‘4’, ‘8’ and ‘16’ samples for the
average.
The other procedure is the same as the pin-type test
lead zero adjustment.

1. Connect the yellow miniature plug of the DCA current adaptor to the meter DCA CLAMP
ADAPTOR jack.
2. USE DCA CURRENT ADAPTOR:
Press the key of the DCA Current Adaptor to turn on the adaptor, the POWER LED will light.
If the LOW BATTERY LED lights, you should replace the battery.
USE PROVA 15 DCA CURRENT ADAPTOR:
Press battery tester key for 3 seconds to select the decimal point of the current reading to
0.000A (for 4A range) or 0.00A (for 30A range).

the LCD then shows 0.0A.
4. Clamp the current transducer (jaw) around one of the conductors under test. Make sure the
clamp jaws are perfectly closed.
5. Read the meter current value.
If no switch operation for 10 minutes, the meter automatically powers off. Auto data memory and
continuous data logging mode will auto disable the auto power off function. For continuous
measurement, in some case it may be necessary to disable the auto power off function.
