i. MEASURING FREQUENCY

CAUTION!

Do not attempt to make a frequency

measurement if a test lead is plugged in the

A or µmA input jack. Instrument damage

and/or personal injury may result.

ARNING!

Never attempt a frequency measurement

with a voltage source reater than 600V

Instrument set-up:

FUNCTION BLACK RED MINIMUM MAXIMUM

TEST LEAD TEST LEAD READING READING

Hz COM V

Hz 0.001Hz 10MHz

Measurement Procedure:

1. Disconnect power to the circuit to be measured.

2. Plug the black test lead into the COM input jack.

3. Plug the red test lead into the V

Hz input jack.

4. Set the rotary switch to the Hz function.

5. Connect the test leads to the circuit to be measured.

6. Reconnect power to the circuit to be measured.

7. Read the frequency on the 183A.

Optional Functions:

HOLD

Scroll between Hz and Duty %.

Freeze the reading on the LCD.

j. MEASURING TEMPERATURE

CAUTION!

Disconnect power to the circuit(s) to be

measured. Discharge the capacitorto be

measured completely before attempting to

measure.

Instrument set-up:

FUNCTION TEMP. TEMP. MINIMUM MAXIMUM

INPUT ADPT. INPUT ADPT. READING READING

TEMP COM µmATEMP 0.1°F 2462°F

0.1°C 1350°C

Measurement Procedure:

1. Remove test leads from the 183A.

2. Plug the “-” terminal of the temperature input adapter

into the COM input jack.

3. Plug the “+” terminal of the temperature input adapter

into the µmATEMP input jack.

4. Set the rotary switch to the TEMP function.

5. Plug a K-type temperature probe into the temperature

input adpater observing the correct polarity.

6. Read the temperature on the 183A.

Optional Functions:

Activate MIN/MAX record mode (page 24).

Activate REL mode (page 24).

Toggle between °C or °F.

HOLD the reading on the LCD.
