 2. FEATURES

○ Model 2417 offers True RMS measurement capability.
○ Designed for measurements of AC Leakage and AC current with

five ranges from 200 mA to 500 A. AC 200 mA range provides a

high resolution of 0.1 mA.

○ Least affected by external magnetic field.
○ Provides dual frequency responses of fundamental 50/60Hz only

or up to 1kHz. The frequency response of up to 1kHz permits

measurements of current with harmonics superimposed on the

fundamental frequency. High frequency current from appliances

such as inverters, switching regulators etc. can therefore be

measured.

○ Data hold function to allow for easy readings in dimly lit or hard-

to-reach locations.

○ Large easy-to-read LCD display.
○ Automatic power off within 30 minutes to conserve battery life.

 5. PREPARATIONS FOR TESTS



WARNING

Always inspect your instrument and accessories for any

sign of damage or abnormality bef ore every use. If any

abnormal conditions exist (eg. cracked cases, display not

reading, etc.), do not attempt to conduct any tests.

5-1 Battery Check

To check the battery voltage set the Power/Range Selector Switch

to OFF position. If the display is clear without symbol "B" showing,

battery voltage is OK. If the display blanks or "B" is indicat ed,

replace the battery according to section 7 for Battery replacement.

NOTE

The instrument automatically turns power off approximately 30

minutes after it is turned on. Therefore the display may be

blank with the Power/Range Selector Switch set to On position.

To operate the instrument, set the switch back to OFF position

and then ON position.

5-2 Data Hold Switch

If the Data Hold Switch is pressed in (DATA HOLD mode), press to

release it.

Otherwise, the display remains frozen. When the instrument is in

DATA HOLD mode, "H" symbol is indicated on the display.

 6. OPERATING INSTRUCTIONS

6-1 Current Measurements



WARNING

● Do not make measurements where the potential is greater

than 600 V AC. This may cause shock hazard and damage

to the instrument or equipment under test.

● The Transformer Jaws are made of metal and their tips

are not insulated. Be especially careful about the hazard

of possible shorting where the equipment under test has

exposed metal parts.

● Do not open the battery compartment cover when making

measurements.



CAUTION

● Take sufficient care to avoid shock, vibration or excessive

force when handling the instrument. Otherwise, precisely

adjusted Transformer Jaws will be damaged.

● When Transformer Jaws do not fully close, never try to

close them by force, but make th em free to move and

try again. If a foreign substance is stuck in the jaw tips,

remove it. If the jaw tips have been deformed, correct so

that each tip is properly aligned. Otherwise, the jaws will

be damaged and warranty may not cover the repair cost.



11



NOTE

● When making current measurements, keep the Transformer

Ja ws ful ly clo se d. Oth er wise, accura te measurements
cannot be taken.

  Maximum conductor size is 40 mm in diameter.

● When measuring larger current, the Transformer Jaws may

buzz. This is not a fault and does not affect the accuracy
either.

(1) Set the Range Switch to the desired "A" or " mA" position.
 (2) Select the desired frequency response. WIDE or 50/60 Hz,

with th e Frequency Selector Switch. (see sect ion 6-2 for
Frequency Selector Switch)

 (3) Press the Trigger to open the Transformer Jaws and clamp

onto a co nductor or conductors as sho wn in Fig . 3. Take
th e readin g on t he dis pl ay. (Th is metho d als o permit s
measurements of leakage current flowing through earthing
conductors and very small current.)

Fig. 3



CAUTION

Do not exceed maximum allowable current on each current range.
(see section 3 for Specifications)



12



NOTE

● For more accurate measurements, place the conductor at

the center of the closed jaws.

● When measuring current on a line or a grounded wire, clamp

onto one conductor only.

 (4) When measuring out of balance leakage current, clamp onto

all conductors except a grounded wire as shown in Fig. 4.

Fig. 4

6-2. Frequency Selector Switch

Model 2417 measures AC currents of:
 (1) 50/60 Hz fundamental frequency only with the Frequency

Selector Switch set to the 50/60 Hz position ("50/60 Hz" is

indicated on the display), or

 (2) 40 Hz to 1 kHz with the Frequency Selector Switch set to the

WIDE position ("WIDE" is indicated on the display)



13



Frequency respo nse of 40 Hz to 1 kHz permits measurements
of current with ha rmonics su perimpose d on th e fundamen ta l
fr eq ue ncy. Hig h f re qu ency current from app li ances suc h as
inverters, switching regulators etc. can therefore be measured.

NOTE

● Model 2417 hasa very good frequ ency response due to

the electrical property of the transformer jaws used for the
instruments.

  Therefore, it measures AC current of not only 50 Hz or 60 Hz

fundamental wave form but also of higher frequencies and
harmonics superimpo sed on the fundamental frequency
when present in the circuit under test. To eliminate the effect
of noise from the high frequency and measure AC current
of 50 Hz or 60 Hz fundamental frequency, a filter circuit is
incorporated into the Model 2417 which works when the
frequency selector switch is set to the 50/60 Hz position.

  It is designed to attenuate frequencies starting from around

100 Hz with an attenu ati on characteri sti c of approx. -24
dB/octave (signal strength declines to one sixteenth of that
at the initial frequen cy when it doubl ed). Recently there
has be en increa sed us age of power throu gh invert er s,
switching regulators, etc. When the high frequency noise
from such appliances leaks or flows into the ground through
capacitors not filtering completely, the earth leakage breaker
may not trip. In such a case the instruments may not give
current readings with the frequency selector switch at the
50/60 Hz position. Therefore, it is necessary to make current
measure ments with t he switch at the " WIDE" posit ion.
When in do ub t as to the pre sence of high freque ncies
an d har mo ni cs that a ff ec t AC c ur re nt measure me nt s,
take current readings with the switch at the 50/60 Hz and
"WIDE" positions respectively and then compare the results
obtained.
