ATTENTION: K10 GAUGES BOTH STRAIN AND QUARTZ OF ALL SIZES:

DURING ASSEMBLE/ DISASSEMBLE, WRENCHES ARE TO BE PLACED ON

THE CLOSEST FLATS. NO PIPE WRENCHES ARE TO BE USED ON

KUSTER MEMORY GAUGES. WISES WITH ROUND HALF CLAMPS ARE

RECOMMENDED FOR FIXING THE GAUGES FOR DISASSEMBLE

PROCEDURES.

IN ORDER TO AVOID TOOL MALFUNCTIONING, O’RINGS UNDER THE

ELECTRONICS HOUSING SHOULD BE REPLACED STRICTLY ACCORDING

THE PROCEDURE, DESCRIBED AT THE END OF THIS MANUAL.

WARNING: ALL ELECTRONIC GAUGES: UNDER NO CIRCUMSTANCES IS THE

TEMPERATURE RATING OF THE BATTERIES TO BE EXCEEDED.

WORK PREPARATION:

1. Make sure that the tool is able to meet the anticipated requirements of the well to be

surveyed, i.e. pressure and temperature limitations.

2. Make sure that the battery temp limit meets the requirements of the well to be surveyed.

3. Check the battery voltage using the supplied battery tester. With the load adapter

attached to the DMM and the battery turn the selector switch to 20 Vdc. Turn on DMM

and read voltage. The load adapter has 380Ω resistor inside which emulates the board.

The voltage of the battery under 380Ω load should be min 3.1 v for the AA type batter

and min 6.1 v for C type. If the new battery has shown very low voltage, the problem

could be in the battery being passivated. In order to depassivate the battery apply Lo

and Hi loads of the tester.

There is another way of checking the battery. Connect battery to the gauge. First you

will get 1 long flash on battery LED. After that, six or less short flashes. Amount of the

short flashes will indicate approximate voltage of battery. For example, if you will get 6

short flashes, it will indicate, that the battery voltage is about 3.6v, which is a maximum

battery charge level. If it will flash 5 times, then the battery voltage is about 3.5v and so

on. Flickering flash with assigned rate will indicate that gauge start sampling. At 1-

second sample rate you will not get a flickering flash, but a regular short one.

Third method of checking the battery is with a help of the software and is explained in the

software manual.

4. Power comm. box either with gauge battery or thru a wallwart. Connect gauge through

interface-box to the computer.

5. You will get 1 long flash and then 4 short flashes on comm. box for strain gauge and 5

flashes for quartz. After that it will continue to flash in communication mode. If you don’t

get right amount of flashes, tool and battery feasibility should be questioned.

6. Program the gauge with desired rate. (See software manual for a more detailed

explanation of programming options).

CAUTION: DO NOT DISCONNECT GAUGE DURING DATA TRANSMISSION.

7. Disconnect gauge from the interface box.

8. Apply a bead of Kuster hi-temp thread lube to all threads and across o’ring glands.

9. Disconnect the buffer tube assembly from transducer sub.
