DESCRIPTION

The Triplett Model 60 A Volt Ohm Milliammeter

(VOM) is a multi range instrument for general electrical and electronic trouble shooting and · measurement. It has been especially designed to satisfy the need for a precision instrument which can stand up under rigorous hard usa g e of the industrial and maintenance environment and at the same time provide a degree of safety in its use heretofore unavailable with an instrument of this kind.

Maintenance is simplified by designing an independent meter module for quick replacement or service and easy t o follow parts layout.

X'TRA RUGGED: Unique design and selection of materials permits the i n strument to withstand the normal acci dents of dropping and rough handling which occur in hard day to day use. The Model 60 A is warranted to with stand an accidental drop up to a five foot height with de viation from its stated accuracy not exceeding

±

4%. The warranty does not include mechanical parts being defaced

( scratched , etc.

) from a drop or normal usage .

OVERLOAD PROTECTED: The instrument has been engineered for significant reduction in the need for ma i nte nance by virtual elimination of parts burn out (other than fuses ), and parts damage from severe mechanical abuse.

Three fuses are employed for unusual protection to the instrument and safety for the user . The 1/ 8 Amp and 1

Amp instrument fuses are used for normal overload con ditions . Spares for each are included in the inst ru ment .

Protection is provided for high energy fault cur r ents be yond the capabilities of the instrument fuses up to the ca pacity of the 2 Amp/ 1000V ( 20 kW) fuse.

SAFETY DESIGNED: Unusual effort has gone into the instrument 1 s design to provide the greatest possible safety to the user .

6 www.SteamPoweredRadio.Com

DESCRIPTION ( cont 1 d.)

The Model 60 A provides a specially engineered internal electrical system to prevent explosive arcs in high energy circuits up to the 2 Amp/ 1000V (20 kW ) fuse capacity . Complete 10sulation of the instrument itself plus a new type test lead are additional safety features .

CONFIDENCE T E ST: A feature built into the instrument for periodic reassurance checks of its meter . While not intended as a comprehensive test of the ins tr ument it does perm i t a high level of confidence

IO the instrument meter if the pointer indicates within the area of the test symbol.

Ranges l1ave been designed to cover nearly all applications with the added convenience of signal level measure ments in decibel decade steps .

The carrying handle can be rotated to provide a st a nd for placing the ins t rument at a viewing angle of app r oxi mately 30 degrees .

A sepa r a t ely sealed ba t te r y compartment permits access to batteries and fuses without removal of the rema i n der of the instrument . In addition, battery aci.ds are sealed off to prevent damage to components . www.SteamPoweredRadio.Com

GENERAL INSTRUCTIONS

INSTALL BATTERIES:

,

1. Loosen

•

screw.

2. Slide cover off.

' 3. Install batteries .

4. Replace cover.

ADJUST POINTER TO ZERO: www.SteamPoweredRadio.Com

With unit in operating posit ion use a screwdriver to adjust pointer for a zero indication.

While keeping the pointer on zero , reverse the rotation of the screw slightly to disengage it. This will reduce the affect of pointer shift under shock.

8

GEN E RAL INSTRUCTIONS {cont'd.)

START WITH HIGHEST RANGE

When the approximate value of the voltage or cur r ent being measured is 11ot known, always start with the highest range to avoid overload and blowing a fuse

.

RANGE CHOIC E

For greatest accuracy choose the range which allows readings to be made in the upper

(right hand ) portion of the scale . Accuracies are rated as percent of full scale so the closer to full scale the better the accuracy .

DO NOT CHANGE SWITCHES UNDER LOAD

Quality switches are used but any switch will arc if changed while under load . Disconnec t the. test probes or shut off the circuit under test before the range switch or polarity switch positions are changed

. This practice will result in increased life and reliability of the instrument .

MEASUREMENT ERRORS

Readings on the £ensitive ranges may some ti mes be different than expected due to thermoelectric or electrochem i cal effec t s .

Readings on the high resistance ranges can be affected by touching the circuit causing the body t o act as a shunting resistor.

Consideration should be given to the loading affect of the instrument when measuring vo l tages from sources of high impedance . www.SteamPoweredRadio.Com

21

MEASURING DECIBELS (dB)

The decibel is a unit that expresses the r atio of power levels . It is mathematically derived to reduce multiplication and division to addition and subtraction, respectively, (e .

g . - 10 dB represents multiplication by 10, 20 dB by 100, 30 dB by 1000). The decibel roughly approximates human hearing ratios. For this reason, it is commo nly used in audio and telephone meas ur ernents.

Because the decibel represents a ratio, there is a reference level. The Model 60-A reference leve l for 0 dB is l milliwatt into a 600 ohm load (. 775 ACV across

600 ohms). Measurements made across load other than

600 ohms are relative measurements .

To measure decibels, connect the Model 60-A the same as for measuring AC voltage (or OUTPUT voltage, if there is DC voltage present). But, read the dB scale instead of the voltage scales. A chart on the dial shows the dB values t o be added to th e reading for the different voltage ran ges. (e .

g. when the selector switch is set to the 30 VAC position, add 20 dB to the indicated value).

As explained above , addition of dB re p resents multiplication of power (or voltage). www.SteamPoweredRadio.Com

22

CONFIDENCE-TEST:

A "Confide n ce-Test feature has been bui1t into the in strument to allow the user to make periodic reassurance checks of the meter. To make the test proceed as follows:
