PH3-LLT MK2 Proving Unit
PH3-LLT MK2 Proving Unit
Product Information
The PH3-LLT MK2 Proving Unit is a device that provides a 500V DC
output voltage (depending on battery condition) with a 10mA DC
output current into 2k. The unit has an LED indication of voltage
active and has dimensions of 41mm (h), 82mm (w), and 157mm (d). It
requires a 9V DC PP3 Alkaline Battery for power supply and has an
IP Rating of 40. The unit is compliant with BS EN 61010
standards.
Product Usage Instructions
Before use, ensure that both the PH3-LLT MK2 and the LLT MK2 are
clean and dry. Visually inspect all parts of the PH3-LLT MK2, if
any parts are damaged do not use the PH3-LLT MK2. Do not hold LLT
(Live Line Tester) MK2 between the hand-guard and the contact
electrode as there is an electrical shock risk. Always confirm that
the LED indicator on the proving unit illuminates when the test is
activated.
For maintenance, clean only with a dry cloth and do not use
solvents. Check the battery contacts and compartment for
electrolytic contamination, and clean any contamination with a dry
cloth. If the item becomes faulty, do not open it; instead, return
it to the manufacturer or an authorized Seaward Service Agent.
To maintain the specified performance, the instrument must be
verified at regular intervals by either the manufacturer or an
authorized Seaward Service Agent. The recommended calibration
period is one year.

be used by competent suitably trained personnel after
due consideration of any hazard involved.
The following symbols are used in these operating instructions and on the PH3-LLT MK2.
Warning of electrical danger! Indicates instructions must be followed to avoid danger to persons.
Important, follow the documentation! This symbol indicates that the operating instructions must be consulted and adhered to in order to avoid danger.
Before use, ensure that both the PH3-LLT MK2 and the LLT MK2 are clean and dry. Visually inspect all parts of the PH3-LLT MK2, if any parts are damaged do not use the PH3-LLT MK2.
Do not hold LLT (Live Line Tester) MK2 between the hand-guard and the contact electrode.
Electrical shock risk! Do not touch terminals!
Always prove the LLT MK2 before AND after use.
Always check that the LED indicator on the proving unit is illuminated whilst testing.
If the equipment is not used in a manner specified in the manual, the protection provided may be impaired.
Do not use without battery compartment cover fitted.
Do not energise the proving unit for longer than 5 seconds, to preserve the battery.

2 Environmental conditions PH3-LLT MK2 was designed to perform tests:
· In a dry environment. · At altitude of up to 2000M. · At temperature of 5-40oC without moisture
condensation.
3 Proving The PH3-LLT MK2 is intended to check if a LLT MK2 functions correctly.
1. Insert each probe of the LLT MK2 inside the PH3-LLT MK2 terminals.
2. Press down on the right terminal (closest to the battery compartment) to switch on the PH3-LLT MK2.
3. Confirm the LED on the PH3-LLT MK2 front panel is illuminating.
4. If LED does NOT illuminate, replace the battery by following 6 Battery Replacement instruction.
5. If LED still does NOT illuminate, this suggests PH3-LLT MK2 is faulty. DO NOT USE.
6. Confirm the Dual LEDs on LLT-PH3 are illuminating. If Dual LEDs are NOT illuminating, this suggests LLT MK2 is faulty. DO NOT USE.
7. Disconnect both probes from the terminals after test is complete.
