The 5000K is set at the factory for a test time of 3 minutes. To change the test time, go to “UNIT CONFIG
1” menu, “TEST TIME A” or “TEST TIME B”, press “ENTER” to highlight the desired hour or minute block,
using the keys set the desired test time. Push “ENTER” again to confirm the time selected. Scroll down to
the “SAVE & EXIT” and hit “ENTER”. This will take you back to the main menu. The time set also
determines the length of test when logging long term pressure tests.

DIFFERENTIAL PRESSURE MEASUREMENT
The 5000K can measure pressure drop across meters, separators, and filters. The method uses an
optional three-way manifold available from Kuhlman Instrument Company. This method uses either
pressure input port, depending on the pressures to be compared. To measure differential pressure,
connect the three-way valve to either pressure port of the 5000K, depending on the pressure in the
system under test. Connect the other two ports on the valve across the device under test, being sure not
to apply more than the maximum specified pressure to either pressure port. Use the ▲and ▼keys to
select “DIFFERENTIAL PRESSURE TEST”. Set the three-way valve to port the first pressure to the
5000K and press “ENTER”. Then set the three-way valve to apply the second pressure to the instrument
and again press “ENTER”. The 5000K will display the first pressure (P1), the second pressure (P2), and
the difference in pressure between P1 and P2. Press “EXIT” to end the test or press “ENTER” to save the
data.
BE SURE THE PRESSURE APPLIED DOES NOT EXCEED THE MAXIMUM ALLOWABLE INPUT
PRESSURE FOR THAT PORT.

LOCKUP AND FLOW TESTING
A lockup and flow test is used to detect leakage through a pressure regulator with no gas flow and the set
pressure at a predetermined gas flow rate. To measure lockup and flow, use the ▲or ▼key to select
“LOCKUP AND FLOW TEST” Press “ENTER” and “APPLY NO FLOW PRESSURE” will be displayed.
When pressure has been applied to the correct port with no gas flowing through the regulator, press
“ENTER”. “APPLY FLOW PRESSURE” will be displayed along with “1: - XX.X” and the no-flow pressure.
Open a valve downstream of the regulator to allow a calibrated gas flow as stated in your company’s
manual of approved procedures. When flow has stabilized press “ENTER” to record the flowing pressure.
MAKE SURE FLOWING GAS IS SAFELY VENTED! The display will show “1:- X.X” and “2:-X.X” for the
respective no flow and flow pressures and “COMPLETE”. Press “ENTER” again to enter the test ID
number. Use the cursor keys to enter the correct ID number then press “ENTER” to show “USER PIN”
and use the cursor keys to enter your PIN. Press “ENTER” to record the test number, your pin and to
store the test data.

LEAK TEST WITH LOG DATA
The data logging function allows the 5000K to log pressure, record pressure change over time. Data will
be logged for the time selected as test time. To enable data logging, scroll to the test menu select either
“LOW PRESSURE TEST W / LOG” or “HIGH PRESSURE TEST W / LOG” display and press “ENTER”.
TEST ID#” is displayed use the scroll keys to enter test ID number/letters, RATE: which is the pressure
sampling interval; you can change the sample rate using the scroll keys. The default sample rate is 00.30.
Press “ENTER “and scroll to continue. To begin a test, connect the pressure source to the port selected.
Press “ENTER” to begin the test. The display will show the initial test pressure (I :), any decrease in
pressure (D :), the current pressure (C :), and will count down the time remaining test time. At the end of
the test, the alarm will sound, the light will flash, and
“T: COMPLETE” will be displayed. Press “ENTER” to display USER PIN” will be displayed. Again use the
scroll keys to enter your PIN. Press “ENTER” to complete the test. This completes the test and stores the
data for printing or transfer to a computer. To stop the test before it is complete, press “ENTER”. Follow
the instructions above to store data from the test.
To set the test time, first scroll to “UNIT CONFIG 1”, press “ENTER” and scroll to “TEST TIME : ”. Press
“ENTER” and use the ▲or ▼key to scroll for the desired test pressure input and press “ENTER”. Use the
scroll keys to select the desired test time in hours and minutes. Press “ENTER” then “EXIT” to return to
the TEST menu to select the desired pressure input port for the test. Be sure the batteries are new or
near full capacity or the 5000K is connected to an external 12VDC or 115VAC supply before beginning
long tests.
