OPERATING INSTRUCTIONS
1. Power Button "
I
"
I
The "
" button turns the thermometer on or off. When entering
REC mode, the power off function is disabled.
2. Button "°C/°F/°K"
Press the °C/°F/°K button to cycle through temperature scale, °C,
°F and °K.
3. Type Selection (thermocouples)
Press the "type" button and the selected symbol will blink which
means in the setting mode.
Press "" button to make right shifts to cycle through K→J→T
→E→R→S→N→L→U→B→ C→mV.
Press "" button to make left shifts to cycle through K→mV→C
→B→U→L→N→S→R→E→ T→J.
Press the "type" button again to choose the selected thermocou-
ple.
4. Backlight " " button
Pressing the button less than two seconds to turn on and pressing
the button again less than two seconds to turn off the backlight in
the LCD. It will turn off after thirty minutes without operation.
Auto power off
It is in the APO mode when the meter is turned on and will turn
off the meter without operation for fifteen minutes. Pressing the
" " button over two seconds to cancel the function. And pressing
the " " button again to activate the APO function.
5. "REL" button
The relative value function can be used for comparing the saved
reference value with other measurements. Press the "REL" button
less than to store the current measurement as the reference value,
and press the "REL" over two seconds to disable the function.
6. "HOLD" button
When HOLD mode is selected, the thermometer holds the present
readings and stops all further measurements. To activate the data
hold mode, press the HOLD button, and "HOLD" is displayed on
the LCD. Pressing the HOLD button again cancels the function,
and the instrument will automatically resume measurements.
When the Hold key is activated, it will stop functions of the other
entire key except Power and Backlight.
7. "T1/T2 SOURCE" buttton
Pressing T1/T2 SOURCE to cycle through T1, T2 and SOURCE.
In the main display the blinking digit is the one to be adjusted,
4
you can push the "" button to make right or left shifts to the
desired position. When incrementing to the utmost range of the
selected thermocouples, the LIMIT will show on the display.
SOURCE is to provide the output parameter settings. There are
2
ten individual temperature setting points in group 0, which can be
set at your desired output point. Use "" to shift the desired
digit to be adjusted and rotate the knob to increase or decrease the
values you want to set. Press the T/C OFFSET to save the set-
tings.
8. "OFFSET" button(Thermocouple offset adjust)
When the main display input is T1 or T2, and socket thermocou-
ple is connected. Press T/C OFFSET less than two seconds the
SET annouciator will appear on the right side of display and enter
the offset adjustment mode. And the blinking digit is the one to
be adjusted. Rotate the knob to the right increasing the values, to
the left side decreasing the values. The maximum range of the
knob is ±5 centigrade. When turning to the utmost range, it will
appear LIMIT symbol on the left side of the display and means
that there is no further incrementing of the offset. Press the T/C
OFFSET over two seconds to save the settings.
9. "MIN/MAX" button
Press MIN/MAX button to enter the MIN/MAX recording mode
and REC shows on the display. The beeper emits a tone when a
new minimum or maximum measurement is recorded. Press the
MIN/MAX button again to rotate through the current
readings:
MAX: The highest measurement recorded.
MIN: The lowest measurement recorded.
MAX-MIN: The difference of the highest and the lowest meas-
urement.
AVG: The average values of the measurements.
Press MIN/MAX button over two seconds to exit the function.
10. Knob usages in the settings
In the TYPE mode, it is used for thermocouples selection to
make right or left shifts to choose selectors. In the SOURCE
mode, it is used to increase or decrease the values of the output
function.
11. PWM Group
Group 0 set
In the OUT mode, press T/C OFFSET over two seconds to set.
LCD display Set CLEAr press T1/T2 SOURCE button to clear
data, display SEt 0-0. In the main display the blinking digit is the
one to be adjusted, you can push the "" button to make right
or left shifts to the desired position. Rotary knob to increase or
decrease the values. Press T1/T2 SOURCE to save the one step
setting. 515 can set 10 step. Press T/C OFFSET exit group set
mode.
Group out
In the OUT mode, press T/C OFFSET less than two seconds. Ro-
tary knob to select step. Press T/C OFFSET exit group out mode.
WARNING
To avoid possible electrical shock, disconnect the thermocouple
connectors from the thermometer before removing the cover.
Maintenance:
Battery Replacement
Power is supplied by a 9 volt "transistor" battery. (NEDA 1604, IEC
6F22). The "
" appears on the LCD display when replacement
is needed. To replace the battery, remove the two screws from the
back of the meter and lift off the battery cover. Remove the battery
from battery contacts.
Cleaning
Periodically wipe the case with a damp cloth and detergent, do not
use abrasives of solvents.
Periodically wipe the meter with soft and mild cloth. Do not use
