Optional Accessories

Tinker & Rasor Models

CPV-2 Voltmeter Analog
CPV-4 Voltmeter Digita

REQUIREMENTS

1. Voltmeter – any high input resistance 20 Megaohm or greater - see “Optional Accessories”.
2. Test Lead – 18 Ga. stranded wire, 8 ft supplied. (longer test lead available upon request)
3. Electrolyte – 4 oz. “Ocean Water” supplied - Potassium Chloride 35:1 mix is okay for storage - see “Maintenance”

PREPARATION & ASSEMBLY

1. Clean Ag/CI element per instruction under “Maintenance” section.
2. Screw end cap with Ag/CI into solid tube (part #118-061) and tighten by hand.
3. Fill tube with “Ocean Water” (part #049-016).
4. Screw ceramic tip assembly into tube and tighten by hand - check “O” rings for leaks.
5. Attach 18 Ga. test lead to top of electrode using knurled nut (supplied).
6. Attach test lead to voltmeter. *

Note:

A. Ceramic tip assembly should soak in electrolyte (Ocean Water) until thoroughly saturated.

B. Ag/CI element must be cleaned, and then soaked in electrolyte at least 15 minutes prior to first use.

*Any quality high resistance meter - 20 megohm or greater such as Tinker & Rasor Model CPV-4 Digital Voltmeter.

OPERATIONS

1. Press the electrodes’ ceramic tip into the soil.
2. Submerge the tip or the entire electrode into electrolyte.
3. Place a sponge soaked in electrolyte under the ceramic tip for dry soil conditions.
4. The ceramic tip assembly must be soaked in electrolyte until thoroughly saturated.

MAINTENANCE & STORAGE

Before Use:

1. The Ag/CI element must be cleaned in distilled water or mild detergent and rinsed in distilled water prior to use.
2. Do not touch Ag/CI element after cleaning.
3. The Ag/CI element should soak in electrolyte for at least 15 minutes before use to stabilize readings.

After Use:

1. To ensure proper readings we recommend the Ag/CI element and the ceramic tip assembly be kept moist during storage. A solid body tube and protective cover are enclosed for this sorage period as well as for use in soil readings.
2. For long-term storage, disassemble or for use after element and ceramic tip have been allowed to dry follow instructions above “Before Use”.

3. Electrolyte 4 oz. – “Ocean Water” supplied - Potassium Chloride 35:1 mix is okay for storage - see “Maintenance”.

PREPARATION & ASSEMBLY

1. Clean Ag/CI element per instruction under “Maintenance” section.
2. Screw end cap with Ag/CI element into tube with holes (part #118-060) and tighten by hand.
3. Screw brass weight (“B”) into tube and tighten by hand.
4. Attach 18 Ga. test lead into waterproof adapter (part #009-010) - see W-7 instructions.
5. Remove knurled nut from top end cap and save.
6. Screw top of electrode into W-7 Waterproof Adapter and tighten by hand.
7. Attach test lead wire to voltmeter.
8. Lower entire electrode into electrolyte and allow to soak for 15 minutes to stabilize readings.

OPERATIONS

1. Submerge the tip or the entire electrode into electrolyte.

Note:

Readings should be taken as close to the structure as possible to minimize I.R. drop. Avoid surface contaminates.

MAINTENANCE & STORAGE

Before Use:

1. The Ag/CI element must be cleaned in distilled water or mild detergent and rinsed in distilled water prior to use.
2. Do not touch Ag/CI element after cleaning.
