I've always tried to take very good care of it. The rubber boot is a bit smudged, and there are a few minor scratches on the multimeter, but there is nothing else wrong with it. It functions perfectly. If I recall correctly, I originally paid around $80 or $85 for it.I'll do my best to answer any questions. Below is a copy of the Specifications section from the manual:

K-TEMPERATURE MODEThis is a special voltage mode, to be used with an optional thermocouple module that can be attached to the meter. This mode automatically converts the 1mV per C or F voltage into a readout that appears as a temperature. In these modes, the unit can show up to 999 C or F.The accuracy of these modes is determined by the external device and the accuracy of the DC volt mode. The temperature range of the newer 1mV per degree C probes is generally between 50 C and 1000 C.FREQUENCYAccuracy400Hz, 4k, 40k, 400kHz, 4MHz:.................................... 0.1% of Reading, 4 in Last DigitSensitivityThe function dial set to LOGIC/Hz (10Hz 4MHz)400Hz, 4k, 40kHz ..................................................................................................... 50 mVrms400kHz ................................................................................................................... 100 mVrms4MHz ...................................................................................................................... 250 mVrmsFor AC voltage frequency, the function dial set to C/ F / V (maximum measuring frequency 1 kHz for signal above 40V)10Hz to 1 kHz .......................................................................................................... 70 mVrms1kHz to 10 kHz ...................................................................................................... 400 mVrmsFor AC voltage frequency, the function dial set to dBm ~ V (maximum measuring frequency 1 kHz for signal above 40V)10 Hz to 200 Hz ..................................................................................................... 300 mVrms200 Hz to 1 kHz .......................................................................................................... 0.4 Vrms1 kHz to 10 kHz ............................................................................................................. 4 VrmsFor AC current frequency400 A/4mA ................................................................................. 10 Hz to 30 kHz: 250 Arms40mA/400mA .............................................................................. 10 Hz to 30 kHz: 25mArms4A/10A ............................................................................................ 10 Hz to 10 kHz: 2.5ArmsDUTY CYCLE (Frequency Range: 10 Hz to 100 kHz)10% 90% (at +5V/-0V Square wave).................................... 2 digits/kHz, 2 in last digitNote: Duty cycle accuracy depends on input signal frequency.
