(7) Maximum Hold
7-1 In maximum hold function the accuracy is changed as following.
Original Accuracy + 10 digitals/ change steps of range .
For example :
At First , the maximum hold reading on display is 100.0mV on 400.0mV range. If a voltage vibration changes the
maximum hold reading to 120.0V. The change steps of range are 3 steps ( 400.0mV to 4.000V to 40.00V to
400.0V) so the accuracy is needed to add 3 change steps of range x 10 digitals / change steps of range = 30 digits.
7-2 On maximum hold mode the accuracy of resistance is specified from 400.0Ω to 400.0kΩrange only.
(8) Auto Power Off
The meter will automatically shut itself off after approximately 30 minutes after power on.
(9) Auto Power Off Disable :
Pressing and hold the ZERO AΩ<button then turn the rotary switch from power off to Ω/<position quickly
(less than one second) that will disable the auto power off.

OPERATION
This instrument has been designed and tested in accordance with IEC Publication 1010, Safety Requirements for
Electronic Measuring Apparatus and has been supplied in a safe condition. This instruction manual contains some
Information and warnings which have to be followed by the user to ensure safe operation and to retain the instru-
ment in safe condition.
3-1 Preparation and Caution before Measurement
1. If the meter is used near equipment that generates electro-magnetic interference, the display may be unstable
or indicate incorrect measurement values.
2. Make sure that the battery is properly connected.
3. The instrument should only be operated between 0℃～ 50℃and at less than 80% R.H. except current
function is operated between 0℃～ 40℃.
4. Do not use or store this instrument in a high temperature or high humidity environment and do not store the
unit in direct sunlight.

17
5. Do not replace battery with power on condition.
6. If the unit is not to be used for a long period of time , remove the battery.
7. Do not forget to turn off after use.
8. Maximum rated voltage to earth for voltage measurement terminals is 600V CAT.III
THIS INSTRUMENT MUST NOT BE USED ON UNINSULATED CONDUCTORS AT A
VOLTAGE GREATER THAN 600V ac/dc.

18
3-2 AC/DC Current Measurement
1. Turning the rotary switch at “A” or “A“ position.
2. Open clamp by pressing trigger on left side of meter.
3. Position clamp around wire or conductor and release clamp trigger smoothly , do not release quickly, make sure
that the clamp is entirely closed. Position the conductors at the center of the clamp jaws for accurate measure-
ment . The clamp must be positioned around only one conductors of a circuit .
If the clamp is placed around two or more current-carrying conductors , the meter reading will be FALSE.
4. For DC measurement , the reading is positive value when the current flows from the upper side to the lower
side of the instrument as Figure 2.
5. For accuracy measurement on DCA mode follow the procedure below
(i) Position clamp around wire or conductor and release clamp trigger smoothly, do not release quickly,
make sure that the wire or conductor is at the center of the clamp.
(ii) Remove the wire or conductor from the clamp.
(iii) Press the ZERO Abutton to zero the reading, effective in DCA mode only.
(iv) Repeat (i).
(v) The positive reading measurement can get better accuracy in DCA mode.
