Main display shows previously set Hi-limit with right most digit blinking.
Change the value of blinking digit with ( ) and ( ) keys and change between “+” and “–” with
“+/-” key. Change the blinking position with ( ) and ( ) key.
Press “ESC” key to end the set-up mode (indicator °C or °F ends blinking, and indicator
“SET” disappears, but keep the previous setting unchanged). Press “CANCEL” key to return to
previous setting but remain in setting mode. Press enter key ( ) to confirm the setting, end the
setting mode of Hi-limit and enter setting mode of Lo-limit with the indicator “Lo” blinking at
upper-right corner.
Set the Lo-limit value same way as setting Hi-limit.
Based on measuring types to set the resolution, there is no decimal point when setting.
8.16 -Setting Time Length of Backlight
Place the rotary switch at position “ ”, LCD shows the indicator “SET” at left. Main display
shows previously set value with right most digit blinking. Change the value of blinking digit with
() and ( ) keys and change between “+” and “–” with “+/-” key. Change the blinking position
with ( ) and ( ) key. Press “ESC” key to end the set-up mode (indicator REL ends blinking, and
indicator “SET” disappears, the previous setting remains unchanged).
Press “CANCEL” key to return to previous setting but remain in setting mode.

Note: When single channel (i.e. T1 or T2 or CHA or CHB) is selected, the selected channel
will be automatically assigned to Main Display and overwrite the previous setting of Main Dis-
play. When multi channel (i.e. “T1 T2” or “CHA T1 T2” or “CHB T1 T2”) is selected the first
channel (i.e. T1 for “T1 T2” or “CHA” for “CHA T1 T2” or CHB for “CHB T1 T2”) will be au-
tomatically assigned to Main Display and overwrite the previous setting of Main Display.
If you do not want this automatic assigned channel shown in Main Display, please re-set the
Main Display (see section 8.1 for setting Main Display). This resetting of Main Display does not
influence the set channel(s) for data logger.

8.11 CHB RANGE-Select the Resolution for Cannel B (CHB)
Channel B can accept the voltage signal up to 2 volts; above 2 volts display shows OL. Place
the rotary switch at position “CHB RANGE”, change among Auto (“--.-.-” and “AUT” is shown
in display), “0.1” (“---.-” and “MAN” is shown in display) and “0.01” (“--.—” and “MAN” is
shown in display).
When “Auto” is selected, the meter will select most suitable resolution between “0.1” and
“0.01”, while the other two, the reading will be fixed in the selected resolution.
8.12 MEM VIEW CLR - Selecting the channel for data logging, Read recorded data and
Clear memory
There are 3 functions in this position “MEM VIEW CLR” :
1. SET function: Select the channels for data logging.
2. VIEW function: To read recorded data.
3. Memory Clear function: Clear memory and erase all the recorded data.
Place rotary switch at position “MEM VIEW CLR”, the meter enter the “Memory Access
Functions Selection Mode” with LCD shows the indicator “MEM” at lower-right corner and a
blinking indicator “SET” at upper-right corner.
Press direction keys or to change the blinking indicator among “SET” (SET func-
tion), “VIE” (VIEW function) and “CLR” (Memory Clear function).
To exit this function, just turn the Rotary Switch to another position.
CLR (Memory Clear function: Clear memory and erase all the recorded data)
When the blinking indicator shows “CLR”, press “ ” key to enter Clear function. The blink-
ing indicator changes to “YES”.
Press “ ” key to clear memory and erases all the data recorded in the memory (this will take
some seconds), and return to “Memory Access Functions Selection mode” with blinking indica-
tor “SET” at upper-right corner.
Or press “ESC” key to abort the job and keep the data in the memory unchanged, and return to
“Memory Access Functions Selection mode” with blinking indicator “SET” at upper-right corner.
Press direction keys or to change the blinking indicator to “SET” (SET function) or
“VIE” (VIEW function), or to exit this function by turning the Rotary Switch to another position.
VIE (VIEW function : to read recorded data)
There are 3 sets of data you can choose to read, namely “SAVE”, “LOG” and “LIMIT”, (cor-
responding to the functions of buttons “SAVE”, “LOG” or “ALMLOG”, respectively. Please re-
fer to section 7.6, 7.7, 7.8 for the functions of these buttons.)
When the blinking indicator shows “VIE”, press “ ” key to enter VIEW function. The
blinking indicator “VIE” disappears. Indicators “READ MEM” and “SAVE” are shown at low-
er-right corner of LCD.

8.9 CHB TYPE-Select the Unit for Channel B
CHB only shows the voltage, and the unit represented by this voltage has to be given. At posi-
tion “CHB TYPE”, change the unit with upward ( ) or downward ( ) direction buttons among
AAA, →˚C→ppt→μs→ms→s→FPM→%RH→%→ppm→mV→V→μA→mA→A→ohm.
The first unit, AAA, can be redefined by user for other special unit, see next section. Press the
confirm button ( ) to select the unit. The selection is kept even power turned off.
CHB is for a transducer with output of 1 mV = 1 “unit”.
CHB always measures the input voltage with mV.
The “unit” is only a human readable indicator for the convenience of user, it does not change
the measurement.
The “unit” can be set as “mV” or “V” or “%RH” or “%” or “ohm” or “ABC”, and it only make
sense when it is set according to the output property of the transducer.
For example if we connect a humidity transducer with output 1 mV = 1 %RH to the CHB
(channel B) of the meter, the “unit” should be set as “%RH”. If user does not do so, then the
the unit becomes meaningless, but the measurement will not influenced.
8.10 CHB PARA-Create Special Unit for Channel B (CHB)
Changing each individual character of “AAA” to one of following can create special units.
(Characters available: upper case characters A to Z, lower case a to z, o, /, %, μ, dot and blank
space).
Place rotary switch at position “CHB PARA”, This user defined unit (set as “AAA” when
shipment) shows at right-upper corner of LCD with the left character blinking. The blinking char-
acter can be changed with upward ( ) or downward ( ) direction buttons.
With right ( ) or left ( ) direction buttons, the blinking can be moved to another character. Af-
ter all 3 character are changed to the desired ones, press confirm button ( ).
