Non-contact voltage

With the red NCV tab on the tip of the meter close

to an AC voltage, press and hold the NCV button.

The NCV LED will light and the beeper will beep. The

closer you get to AC voltage, the louder the beep.

The NCV function is sensitive enough to detect

24VAC on thermostats.

Hi voltage indicator

In any VAC/VDC range, when you touch a voltage

greater than 30V, the beeper will beep and the red Hi-

V LED will blink. BE CAREFUL!

Microamps

For measuring the flame diode current in a heater

control.

Capacitance

For

motor-start

and

motor-run

Disconnect the capacitor from power first. Short the

terminals to discharge the capacitors. Disconnect

any resistors that might be between the terminals of

the capacitor.

MIN/MAX

Press MIN/MAX once to begin recording MIN and

MAX. Press MIN/MAX to select current reading's MIN

or MAX. Hold down for 2 seconds to exit MIN/MAX

function.

Temperature

Plug any K-type thermocouple directly into the

meter to measure temperature. Temperature meas-

urement will be accurate even in fast changing envi-

ronments because of excellent temperature compen-

sation. One thermocouple is included. No adapter is

required.

Backlight (HS36)

Press the

button to activate the backlight for

approximately 60 seconds.

For your safety...

General: Disconnect the test leads before opening

the case. Inspect the test leads for damage to the

insulation or exposed metal. Replace if suspect.

Never ground yourself when taking electrical meas-

urements. Do not touch exposed metal pipes, outlets,

fixtures, etc., which might be at ground potential.

Keep your body isolated from ground by using dry

clothing, rubber shoes, rubber mats, or any approved

insulating material. When disconnecting from a cir-

cuit, disconnect the "RED" lead first, then the com-

mon lead. Work with others. Use one hand for test-

ing. Turn off power to the circuit under test before cut-

ting, unsoldering, or breaking the circuit. Keep your

fingers behind the finger guards on the probes. Do

not measure resistance when circuit is powered. Do

not apply more than rated voltage between input and

ground.

All voltage tests: All voltage ranges will withstand

up to 600V. Do not apply more than 600VDC or

600VAC.

AC tests: Disconnect the meter from the circuit

before turning any inductor off, including motors,

transformers, and solenoids. High voltage transients

can damage the meter beyond repair. Do not use

during electrical storms.

Maintenance

Clean the exterior with clean dry cloth. Do not use

liquid.

Battery replacement: When the multimeter dis-

plays "

" the battery must be replaced. Disconnect

and unplug leads, turn meter off, and remove the bat-

tery cover. Replace the battery with a NEDA type

1604 9V battery.

Fieldpiece HS36 True RMS Digital Multimeter

True RMS (HS36)

Digital multimeters use two different types of AC

sensing. The most common is average sensing, nor-

malized to a true RMS value of a sine wave. The

other is true RMS sensing. The actual true RMS

value is sensed for a wave form within the limits of

the crest factor. Either sensing method will give the

same results on a clean sine wave but they may dif-

fer on a non-sinusoidal waveform.

Field °F calibration

For accuracies of ±1°F, calibrate to a known tem-

perature. A glass of stabilized ice water is very close

to 32°F (0°C) and is usually very convenient but any

known temperature can be used.

1. Select the 400°F range.

2. Remove back case and hold the battery in place

capacitors.

with a rubber band so terminals are touching.

3. Stabilize a large cup of ice water.

4. Immerse the thermocouple probe and let it stabi-

lize.

5. Adjust VR3 (lower right corner of PCB) to get

close to 32°F (0°C) then adjust VR2 (left of VR3)

to get within 0.1°F (0.05°C) of 32°F (0°C).

6. To calibrate in °C, close the jumper that is to the

left of VR3.

Disable auto off

Set to OFF position, press and hold RNG (HS35)

or MIN/MAX (HS36) button while turning rotary dial

to desired range position. Release the button when

LCD displays normally. Note: "APO" annunciator will

be missing from the display. The Auto Power Off

mode is on when "APO" indicated on the display.

Attach to Fieldpiece accessory head

Connect your Fieldpiece accessory head directly

to the top of HS series and switch to range indicated

by head.

Limited warranty

This meter is warranted against defects in materi-

al or workmanship for one year from date of pur-

chase. Fieldpiece will replace or repair the defective

unit, at its option, subject to verification of the defect.

This warranty does not apply to defects resulting

from abuse, neglect, accident, unauthorized repair,

alteration, or unreasonable use of the instrument.

Any implied warranties arising from the sale of a

Fieldpiece product, including but not limited to

implied warranties of merchantability and fitness for a

particular purpose, are limited to the above.

Fieldpiece shall not be liable for loss of use of the

instrument or other incidental or consequential dam-

ages, expenses, or economic loss, or for any claim of

such damage, expenses, or economic loss.

State laws vary. The above limitations or exclu-

sions may not apply to you.

Service

Return any defective HS35/36 to Fieldpiece for

warranty service along with proof of purchase.

Contact Fieldpiece for out of warranty repair charges.

Caution, risk of electric shock

Caution, refer to manual.

Ground

Double insulation

Using & storing test leads

Because the wire insulation is silicone the leads

will stay flexible in cold weather and will not melt if

bumped by a soldering iron.

Disconnect top half of test lead and plug tip direct-

ly into meter to make voltage testing easy. Use with

included alligator clip (ASA2) as shown for even eas-

ier operation.

For convenient lead storage, wrap the leads as

shown. Pull leads around front between overhanging

tips, twist, and pull over one of the lead plugs.
