1. INTRODUCTION
1.1 Introducing the economy series
Thank you for purchasing the Temp 4/5/6 meter. These microprocessor-based
handheld meters are economical and easy to use. They are available in three
models:
•The Temp 4 uses *YSI 400 series thermistor temperature sensor
•The Temp 5 uses 100K thermistor temperature sensor
•The Temp 6 uses PT100 ohm (Platinum) RTD temperature sensor
All Temp 4/5/6 meter series feature:
•Large LCD for clear and easy reading
•Readings in
o
C and
o
F (selectable)
•Minimum and maximum temperature display
•Minimum and maximum hold mode
•Low battery indicator
•Hold function, freezes measured reading
•User calibration - offset adjustment
•Built-in memory backup; calibration and other information remain if battery
is disconnected
•Temp 5 meter allows user selection of most suitable temperature curve for
its thermistor sensor
This instruction manual is organized for quick reference with step-by-step
procedures that give you thorough review of the various features and meter
operations.
Included with your meter are a temperature sensor (Temp 5 only), rubber boot,
4 alkaline “AAA” batteries, an instruction manual and a warranty card. To order
other accessories, please refer to Section on Accessories for more information.

2. GETTING STARTED
2.1 Description of Keypad Functions
Temp 4/5/6 meters have six keys on its splash-proof keypad. These keys
include ON / OFF, CAL, HOLD / ENTER,
o
C/
o
F, MAX /S(UP) and MIN /T
(DOWN) keys.
ON/OFF: Powers meter ON or OFF. Meter directly enters measurement mode
when you turn it on.
CAL: Allows temperature calibration of the meter.
HOLD/ENTER: Freezes the measured reading; confirm calibration value.
MAX/S(UP) and MIN/T(DOWN):Momentarily displays meter’s maximum and
minimum temperature; enter maximum or minimum hold mode; scroll up and
down in calibration mode.
o
C/
o
F: Switches between
o
C and
o
F in measurement mode.
2.2 Description of LCD Annunciators
The Temp 4/5/6 meters have a large custom LCD that consists of 4-digit
segments and operation annunciators for
o
C and
o
F. Other indicators include
“MIN’, “MAX”, “HO” (when the HOLD function is activated) and “LO” (low battery
condition).

2.3 Inserting & Removing the Rubber Boot
1. To remove meter from rubber boot, push out from the bottom edges of
meter until it is completely out of boot. Ensure that the connector of
temperature sensor is not connected.
2. To insert meter into rubber boot, slide in from the top of meter before
pushing the bottom edges of meter down to set it into position. Lift up the
stand at the back of meter for bench top applications if necessary.

2.4 Inserting New Batteries
The battery compartment is found at the back of instrument. To open the battery
compartment, push in the direction of arrow and lift up the cover. Note the
polarity of battery before inserting into position. After replacement, place cover
back and press down until it locks tight.

2.5 Battery Replacement
A “LO” annunciator in the LCD alerts you when battery power is running low.
Replace with the same type as recommended by the manufacturer.
Caution: Power off the meter when changing battery.
2.6 Connecting the Temperature Sensor
To connect a temperature probe into the meter, align the connector of probe to
the meter’s socket and push fully until it is in position.
Note: Both the Temp 4/5 use phono jacks while the Temp 6 uses a 3-pin
connector with a locking mechanism.

2.7 Switching the Meter On
1. Press ON/OFF key to power up your meter. All the LCD segments display
momentarily as the meter performs a self-diagnostic test, per shown in
section 2.2. The LCD then switches into measurement mode.
2. The LCD displays “oPEn” if the temperature sensor is faulty, or there is an
open circuit. Please refer to section on Troubleshooting if in doubt.

3. CALIBRATION
3.1 Temperature Calibration
The temperature sensor included (only for Temp 5) with your meter is factory
calibrated. Over time, the temperature calibration may drift and the probe
requires recalibration. The Temp 4/5/6 meters allow you to have a 1-point
calibration as fine adjustment by changing its offset value. This is useful if you
replace the probe and should recalibrate the probe to the meter.
3.1.1 Temperature Calibration using Offset Adjustment
1. Connect your temperature probe to the meter. Dip the probe in a constant
temperature bath or a liquid whose temperature can be checked with a
thermometer known to be accurate. For best accuracy, place the probe and
thermometer in a constant temperature bath.
2. Turn on the meter. Make sure that the meter is in the measurement mode.
Press CAL key to enter temperature calibration mode. The LCD shows
“CA” momentarily and the displayed reading flashes.
.
°C
3. Press Sand Tkeys to adjust the displayed value until it matches the
correct desired temperature. The Sand Tkey will scroll to the maximum
allowable value (maximum adjustment is ±5
o
C from factory default).
4. Press ENTER key to confirm calibration. The LCD displays “CO”
momentarily, and the meter then reverts to measurement mode.

3.1.2 Temperature Curve Selection (Temp 5 Meter Only)
In the event temperature probe has drifted too far from its original characteristic
– due to age and use or if the probe is being replaced, it may be a good idea to
match probe to the best curve. There are 3 curves programmed in the unit. To
choose the curve, proceed as follows:
1. Connect your temperature probe to the meter. Dip the probe in a constant
temperature bath or a liquid whose temperature can be checked with a
thermometer known to be accurate. For best accuracy, place the probe
and thermometer in a constant temperature bath.
2. Turn on the meter. Make sure that the meter is in the measurement mode.
Press CAL key to enter calibration mode. The LCD shows “CA” and the
reading flashes.
3. Press
o
C/
o
Fkey to enter curve selection mode. Press the
o
C/
o
Fkey again
to scroll through three temperature curves (low, mid. high). Each press will
take you through one curve. Choose the curve which gives you a reading
closest to the actual value (of the bath or thermometer).
4. Press ENTER key and the curve selection is complete. The unit will display
“CO” and revert to the temperature calibration mode, with the display still
flashing.
5. Press Sand Tkey to make fine adjustment until the display shows the
correct desired temperature. The Sand Tkey will scroll to the maximum
allowable value (maximum adjustment is ±5
o
C from factory default).
6. Press ENTER key to confirm calibration. The LCD displays “CO”
momentarily, and the meter then reverts to measurement mode.

5. PROBE CARE AND MAINTENANCE
For best results, always clean the temperature probe with clean tissue paper
after measurement to keep the probe in good working condition. Wash the
probe thoroughly with tap water if necessary to wash off any residue. Should
there be any thin oil film sticking on the probe, wash with mild detergent or soap
and warm water. Rinse probe thoroughly under running water. Blot it dry and
clean off with clean tissue.
To remove the probe, simply hold firmly onto the probe’s plastic holder and pull
the connector out of the meter’s socket. Store both the probe and meter into its
original packaging when not in use.
