To ensure that the meter is used safely, be sure to observe

the instruction when using the instrument.

1. Never use meter on the electric circuit that exceed 6kVA.

2. Never apply an input signal exceeding the maximum rating

input value.

3. Never use meter if the meter or test leads are damaged or broken.

4. Pay special attention when measuring the voltage of AC 33

Vrms (46.7V peak) or DC 70V and over avoid injury.

5. Never use meter for measuring the line connected with equip-

ment (i.e. motors) that generates induced or surge voltage

since it may exceed the maximum allowable voltage.

6. Never use uncased meter.

[1] SAFETY PRECAUTIONS

*Before use, read the following safety precautions.

1-3 Overload protections

*<6A: Continuous measurement is possible. >6A: Cool down DMM

for 3 minutes after the measurement for 1 minute.

17. Be sure to use a fuse of the specified rating or type. Never use

a substitute of the fuse or never make a short circuit of the fuse.

18. When connecting and disconnecting the test leads, connect

the ground lead (black one) first. When disconnecting them,

the ground lead must be disconnected last.

19. Always keep your fingers below the finger guards on the

probe when making measurements.

10. Be sure to disconnect the test pins from the circuit when

changing the function.

11. Before starting measurement, make sure that the function and

range are properly set in accordance with the measurement.

12. Never use meter with wet hands or in a damp environment.

13. Do not use the device near an item of strong electromagnetic

generation or a charged item.

14. Never open tester case except when replacing batteries or

fuse. Do not attempt any alteration of original specifications.

15. To ensure safety and maintain accuracy, calibrate and

check the tester at least once a year.

16. The multimeter is restricted to indoor use only.

[4] DESCRIPTION OF FUNCTIONS

4-1 Function Switch

Turn this switch to turn on and off the power and to select the

functions of "V •dBm/V /mV/Hz •%//Ω• //A•mA/µA".

4-2 Auto Power Off

The Auto Power Off mode turns the meter off automatically to

extend battery life after approximately 17 minutes of no activities.

Activities are specified as:

1) Changing sw position or pressing a button.

2) Significant measuring data readings of around 10% of range.

To wake up the meter from Auto Power Off:

Press the RECORD, CAPTURE, ∆REL or 500000 button momen-

tarily. Alternatively, disconnect the measured subject from the

DMM temporarily, set the rotary switch to the OFF position, then

set it back on the measurement target item, and connect the

measurement subject again.

To disable the Auto Power Off feature, press the RANGE button

while turning the function switch on.

Note:

Always turn the function switch to the OFF position when the

meter is not in use.

4-3 Low Battery Indication

If the internal battery has been consumed and the internal battery

drops below approx. 7V, Battery mark is shown in the display.

4-4 Measurement Function Select

When the SELECT button is pressed (), the functions change

as follows.

•In the case of V /dBm, the modes change as:

VdBm V .

•In the case of V/ , the modes change as:

V V V .

•In the case of mV / / , the modes change as:



•In the case of Hz/%, the modes change as:

4-5 Range Hold

Press the RANGE button momentarily to set the manual range

mode then 'AUTO' disappears in the display. In manual range

mode, press the button again to step through the ranges. To

return to the auto mode, press the button for 1 sec. or more then

AUTO is shown.

Note:

Manual mode is not available in Hz measurement.

4-6 Data Hold

When the HOLD button is pressed, the data display at that time is

hold (' ' is shown on the display). The display will not changed

while the function is active. Press the button again to cancel the

function. (' ' on the display disappears.)

4-7 Set Beeper Off

Press the Hz button while turning the function switch on to disable

the Beeper feature.

However continuity and mis-insertion alarm function remain.

4-8 RS232C Interface

The instrument equips with an optical isolated interface port at the

back of meter body for data communication. Optional accessories

KB-RS2a (RS232 cable), KB-USB2a (USB cable) and PC Link or

PC Link Plus (software), are required for Data logging system.

Refer to an help in the PC Link or PC Link Plus for further details.
