INTRODUCTION

The Wavetek digital multimeter HD160B is a Heavy Duty 4-digit, autoranging, AC­coupled true RMS measuring instrument that measures voltage, current,
resistance, continuity and diode junctions. It also has a Safety Tester™ to indicate
that a voltage is present, even if the meter’s battery is dead. Menu selection allows
Range Lock, Probe Hold, Relative Measurement, Auto Min Max Measurement and
backlight ON/OFF. The instrument is completely sealed.

WARNINGS AND PRECAUTIONS

■ This instrument is EN61010-1:1993 certified for Installation Category III,
1500VDC/1000VAC. It is recommended for use in distribution level and fixed
installations, as well as lesser installations, and not for primary supply lines,
overhead lines and cable systems. ■ All inputs are protected against continuous
overload conditions up to the limits of each function's stated input protection (see
specifications). Never exceed these limits nor the ratings marked on the
instrument itself. ■ For voltage measurements, the circuit under test must be
protected by a 20A fuse or circuit breaker. ■ Exercise extreme caution when:
measuring voltage >20V, current >10mA, AC power line with inductive loads, AC
power line during electrical storms. High voltages can be lethal and high voltage
transients may occur at any time. ■ Operator injury or damage to the multimeter
may occur during current measurements if the fuse blows in a circuit with open
circuit voltage >600V (500V in mA input). ■ Always inspect your DMM, test
leads and accessories for signs of damage or abnormality before every use. If an
abnormal condition exists (broken or damaged test leads, cracked case, display
not reading, etc.), do not use. ■ When testing for voltage or current, make sure
these ranges function correctly. Take a reading of a known voltage or current first.
n Never ground yourself when taking measurements. Do not touch exposed metal
pipes, outlets, fixtures, etc., which might be at ground potential. Keep your body
isolated from ground and never touch exposed wiring, connections, test probe
tips, or any live circuit conductors. Do not use the Flex-Strap to attach the meter
to your body. ■Always measure current in series with the load – NEVER connect
the multimeter ACROSS a voltage source. Check fuse first. ■ Never replace a fuse
with one of a different rating. ■ Do not operate instrument in an explosive
atmosphere (flammable gases, fumes, vapor, dust.) ■ Do not use this or any
piece of test equipment without proper training ■ CRT SERVICE SAFETY
REMINDER : A potential danger exists when measuring voltages in the horizontal
output and damper stages of CRT equipment. (High voltage transients greater than

- 2 -

8,000 V). Refer to your CRT service manual for proper servicing instructions.

PREPARATION FOR USE – UNPACKING

Your shipping carton should include the multimeter, a holster with flex strap, one
test lead set (one black, one red), one 9V battery (installed), one spare fuse, a hex
wrench (held inside holster) and this manual. If any of the items are damaged or
missing, immediately return the complete package to the place of purchase for an
exchange.

PROTECTIVE HOLSTER

The holster/tilt stand provides additional protection of the meter from accidental
falls and provides greater ease of use. Both test lead probes can be attached to the
holster for storage. One probe can be attached for measurement, holding the
meter with probe in one hand and the second probe in the other hand.

OVERLOAD INDICATION

Input Overload (highest range in autoranging) is
indicated by “I.OL” and a continuous tone. Remove
test leads from the measurement setup as the input
is beyond the range of the meter.

Display Overload (input exceeds the selected range
while range is locked) is also indicated by “I.OL”. Select the next higher range
until a value is displayed, or return to autoranging. If overload still exists in the
highest range, remove test leads from the measurement setup as input is beyond
the range of the meter.

Note: In both instances, overload indication is normal in the OHMS and continuity
ranges (no sound) when the leads are not connected to anything or when the
measured value is higher than the selected resistance range.

Audible Feedback

The meter emits a single beep when a parameter is changed, a “valid” front panel
button is pushed, or Auto Min Max or Probe Hold values are updated. A double
beep indicates a dangerous input voltage (>30VAC or 60VDC).

The meter emits a continuous tone in the case of input overload, for continuity
measurement when resistance is <50Ω, and for current measurements, when the
10A input is used and the current exceeds 10A.

Analog Bargraph

The analog bargraph indicates which percentage of the range a displayed
measurement relates to. The zero segment is lit when the instrument is turned on.
If the input is less than 40% of range, each segment equals 1% of range. If the
input is above 40% of range, each segment equals 10% of range. Example: a
300mV input in the 1V range (30%) is represented by 30 segments
( ); a 600mV input (60%) will be represented by 6 segments
().

Exception: in the 40mA range, one segment represents one mA.

SAFETY TESTERTM(See Fig. 1)

The Safety Tester™ is designed to provide a quick sure look at a circuit for
voltages up to 480VDC or ACrms. It will indicate the five voltage levels even if
the meter has a dead battery or blown fuses. ¶ Position the Range Selector
Switch in the Safety Tester™ position. Â Connect the test leads to the COM and
VΩ inputs then across the circuit to be tested. ’ Note which, if any, LED(s) is(are)
lit for voltage level.

WARNING - The Safety Tester™ is designed as additional level of fail-safe
protection, but should not be trusted on a meter which has known operational
problems or has been damaged. It can not indicate the presence of voltage over

DC AND AC VOLTAGE MEASUREMENT (See Fig. 2)

❶ Connect test leads as shown in figure 1. ❷ Turn function selector switch to V
or V . ❸ Touch Probe tips across voltage source (in parallel with circuit). ❹
Voltage value will appear on Digital Display along with the voltage polarity (for DC).

True RMS AC Measurements: Model HD160B is an AC-coupled True-RMS
measuring meter. It measures the true RMS value of distorted AC voltage or
current signals. The Crest Factor handling capability is shown in

Fig. 2

Table 1. The Crest Factor is the Peak Voltage divided by the RMS voltage.
Note: To accurately measure a DC voltage with an AC component, measure the
AC component first with selector switch set to V . Note the measurement and
range used. Switch to V , activate Range Lock (see Menu Functions, page 12)
and select a range equal to or higher then the V range used previously. Note the
measurement. The result is the measured AC Voltage on top of the measured DC
component. (Max input is 1500V for any combination).

DC AND AC CURRENT MEASUREMENT (See Fig. 3)

❶ Connect red test lead to the mA input for current measurements up to 40mA or
to the 10A input for current measurements to 10A. Connect black test lead to
COM input connector. ❷Set the Function Switch to A or A as required. ❸
Open circuit in which current is to be measured (voltage between this point and
ground must not exceed 600V on 10A input or 500V on mA input). Securely
connect test leads in series with the load. ❹ Turn on power to circuit being tested.
➎ Read current value on Digital Display.

Note: If, in the 10A range, the meter is exposed to current greater than 10A, it
should be turned off and allowed to cool for at least 10 minutes

Incorrect Input Warning: “FErr” is displayed when a test lead is connected to
current input, but the selector switch is not set to a current range.

DIODE AND CONTINUITY TEST (See Fig. 5)

The diode test measures the voltage drop across a diode junction. ❶ Connect the
test leads as shown in figure 5. ❷ Set the Function/Range switch to . ❸
Apply probe tip of red lead to the anode and of black lead to the cathode of the

diode. ❹ The meter’s display indicates the forward voltage drop (approx. 0.6V for
silicon diode or 0.4V for germanium diode). An open diode is indicated by “I OL”.
➎ Reverse test lead connections to the diode to perform a reverse bias test. “I OL”
indicates a good diode. Notes: “I OL” for both reverse and forward bias tests
indicates an open diode. A low voltage reading for both bias tests indicates a
shorted diode. If the diode is shunted by a resistor of 1000 ohms or less, it must
be removed from the circuit before taking the measurement. Bipolar transistor

WARNUNGEN UND VORSICHTSMAßNAHMEN

■ Dieses Gerät ist EN61010-1:1993 zertifiziert für Installationsklasse III,
1500VDC/1000VAC. Anwendung ist empfohlen auf Verteilerebene und festen
Anlagen sowie untergeordneten Systemen, jedoch nicht für Starkstromnetze und
Hochspannungsanlagen. ■ Überschreiten Sie nie die kontinuierlichen
Überlastgrenzen der verschiedenen Meßfunktionen (siehe Spezifikationen) oder
andere Grenzen welche auf dem Gerät markiert sind. ■ Für
Spannungsmessungen muß der Meßkreis mit einer 20A Sicherung oder einem
Trennschalter abgeschirmt sein. ■ Vorsicht beim Messen von Spannungen >20V
// Strömen >10mA // Netzstrom/-spannung bei induktiver Last oder bei Gewittern
// Strom, wenn die Sicherung durchbrennt in einem Schaltkreis mit
Leerlaufspannung >600V (>500V beim mA Eingang) // beim Messen an
Bildröhrgeräten (hohe Spannungsspitzen) ■ Unsersuchen Sie Gerät, Meßkabel,

ÜBERLASTANZEIGE

- 20 -

Eingangs-Überlast (höchster Bereich in
automatischer Bereichswahl): “I.OL” Anzeige und
Dauerton. Messung unterbrechen da der Meßwert
die Eingangsgrenze überschreitet.

Bereichs-Überlast (Der Eingang überschreitet
den betreffenden Bereich bei manueller Bereichswahl - RANGE LOCK): “I.OL”
Anzeige. Höheren Bereich wählen oder Messung unterbrechen.

Anmerkung: Überlastanzeige ist normal bei Widerstandsmessung wenn
Meßkabel/-spitzen frei stehen oder wenn der Meßwert den Bereich überschreitet.
In allen anderen Fällen ist die Ursache der Überlast sofort zu entfernen. Höheren
Bereich wählen oder Messung unterbrechen.

ANZEIGENSYMBOLE

Gefährliche Eingangsspannung - über 30VAC oder 60VDC (auch

doppelter Biep-Ton)

Polaritätsanzeige
Batterie entladen

MENÜFUNKTIONEN - Siehe Seite 29

AKUSTISCHE ANZEIGEN

Das Gerät gibt einen Einzelton ab bei Funktionswechsel, bei Aktivierung einer
“validen” Taste und wenn neue Auto Min Max- und Anzeigenspeicherwerte erfaßt
werden. Ein Doppelton zeigt eine gefährliche Eingangsspannung (über 30VAC
oder 60VDC) an.

Ein Dauerton wird abgegeben bei Eingangsüberlast und bei Durchgangsmessung,
wenn der Widerstand unter 50Ω liegt. Wenn beim RMS225 im 10A Bereich
gemessen wird, wird ein Dauerton abgegeben wenn der Eingangsstrom 10A
überschreitet.

BALKENANZEIGE

Die Balkenanzeige gibt an welchem Prozentwert des Meßbereiches der Meßwert
entspricht. Das erste Segment leuchtet beim Einschalten des Gerätes auf. Liegt der
Eingang unter 40% des Meßbereichs, dann entspricht jedes Segment 1% des
Meßbereichs. Liegt der Eingang über 40% des Meßbereichs, dann entspricht
jedes Segment 10% des Meßbereichs. Beispiel: Ein Eingang von 300 mV im 1V

Bereich (30%) wird durch 30 Segmente angezeigt ( ); ein Eingang

0102030
