Instruction Manual

Description The BathyCorrometer® Pro’ (BCM) is an underwater corrosion voltmeter powered by an integral, rechargeable battery pack. The unit is fitted with a 3½ digit, high impedance (1MΩ) liquid crystal display (LCD) voltmeter. The unit can read voltages from 0.000V to -1.999V DC. The structure to water potential is detected by an internal Ag/AgCl/seawater half-cell electrode of robust and proven construction. The reference electrode is mounted behind the red protective nose cone and sited 5cm from the probe tip. Probe Tips Six stainless steel probe tips are supplied with the instrument....

Unpacking Please check that all items are present in the kit by referring to the relevant datasheet for your kit (Basic, Standard or Complete). If any items are missing contact your supplier immediately. The packaging should be kept for future use should the unit need to be returned for repair or put into storage. Operation BathyCorrometer® Pro’ unit Fit a stainless steel pointed probe tip to the end of the instrument using a smear of silicone grease to prevent damage of the O-ring seal. Use the spanner provided to ensure the probe tip is tightened fully. Smear the shorting plug pins with...

Instruction Manual BathyCorrometer® Pro’ Charger The BathyCorrometer® Pro’ battery charger is supplied with several mains plug options (European, UK, USA, Australia, Asia), select the correct configuration for your mains supply, clicking it into position on the charger input. It is recommended that the BathyCorrometer® Pro’ is charged for 8 hours before initial use. Connect the charger to the BathyCorrometer® Pro’. Connect the charger to the mains supply, the small indicator light on the charger should illuminate. If the indicator does not illuminate check the connection to the...

Calibration IMPORTANT BathyCorrometer® recalibration should only be undertaken by Buckleys trained and approved technicians with access to the appropriate electrical and pressure testing equipment. Recalibration by unqualified technicians will invalidate the BathyCorrometer’s warranty. Electronics Calibration Check 1. The electronics in the BCM/BCM Pro’ can be checked with the aid of the CalChecker Pro’. When connected to the BCM/BCM Pro’, this produces a precision voltage of -1.900V DC which can be compared with the reading on the BCM/BCM Pro’. This is just a check as the electronics are...

Instruction Manual The effect of this is that the voltage reading obtained by a correctly-functioning silver-silver chloride (Ag-AgCl) half-cell in 3% sea water at 25C will be approximately -54mV for the K-SAT cell. As with all Silver-Silver Chloride chemistry, the exact voltage obtained will depend on the conditions, particularly water temperature and salinity. A tolerance of +/10mV for the K-SAT cell indicates acceptable performance. The following instructions should be used to check the calibration of the BathyCorrometer® Pro’. Screw cap Unscrew the white Delrin probe cone. Smear the...

The voltage difference between the K-SAT electrode and the internal silver/silver chloride electrode can be read directly off the digital display on the BCM/BCM Pro’. The test should be repeated with another K-SAT to confirm the accuracy of the internal Ag/AgCl/seawater half-cell electrode. Plastic container Voltage difference between KSAT reference electrode and Seawater test solution 3% salinity Remove the K-SAT cells, refit their protective caps, wipe down and store in a cool dark place. Note: The protective caps should ALWAYS be fitted whenever the K-SAT cells are not in use. Note: The...

Instruction Manual Using Zinc & Magnesium test blocks Verification of the operation of the BCM Pro’ can be carried out using Zinc and/ or Magnesium test blocks. Potential measurements taken should be noted to check if any significant variation occurs. Differences in the order of 10mV or so between readings are quite possible and will mainly be caused by variations in water salinity at different locations and/or changes in water temperature. As a guide, readings taken in a 3% salinity solution at ambient temperature of 25°C are as follows: Zinc (Zn) = -1.00 to -1.08V Magnesium (Mg) = -1.40...

Check the O-rings on the inside and outside of the white delrin probe cone and replace if necessary. Smear the O-rings with a little silicone grease, and replace the white delrin probe cone onto the tie rod. Replace the stainless steel probe tip. Maintenance Very little maintenance is required apart from keeping the unit clean and ensuring that the holes in the red nose cone are kept clear of any obstructions such as dirt or marine growth etc. The calibration of the BCM/BCM Pro’ electronics and the reference electrode should be checked at regular intervals. If the unit has been used in a...

Instruction Manual Electromagnetic compatibility European Union Directive The BathyCorrometer® Pro’ and its charger do not generate RF energy and therefore will not interfere with other electronic equipment. The BCM is a sensitive voltmeter which when used under water will be screened from electromagnetic interference by the sea. However, when on the surface during calibration, interference may cause the BathyCorrometer® Pro’ to give incorrect readings. If this is the case, investigate to see if any transmitting equipment is in operation ie. radio telephones, radar or if any arc welding is...
